Actin confirmed equal loading; blots are representative of at least two independent experiments. Related to Fig 4.B–EqRT–PCR analysis revealed that hypoxia increased the expression of known YAP target genes AREG, BCL2L1 (BCL‐XL), CTGF & CYR61. Representative experiments are shown. Representative examples of n = 3 independent experiments are shown; data are presented as mean ± SD.FIncreased expression of YAP Ser397 in GPRC5A‐depleted cells was overridden by expression of constitutively active RhoA (G14V) in hypoxia. Expression of dominant negative RhoA (T19N) did not further increase YAP Ser397 phosphorylation in response to GPRC5A depletion.GDarker exposure of the GPRC5A blot in Fig 4I, confirming expression of 30–40 kDa & 80 kDa species. Note that YAP siRNA partially diminishes GPRC5A in line with the existence of positive HIF‐GPRC5A‐YAP feedback loop.

Background: Carbonic Anhydrase IX/CA9

Carbonic anhydrase alpha, isozyme IX, belongs to a family of zinc-containing metalloproteins which hydrate carbon dioxide to generate bicarbonate ions and protons (1). This main catalytic function allows carbonic anhydrase IX to participate in cellular pH regulation. The large family of carbonic anhydrase metalloproteins includes three major classes which have been identified based on sequence and structure analysis. The alpha class is a monomer found in mammals. The beta class may occur as a dimer, tetramer, hexamer or octamer and is found in plants, algae, and bacteria. Lastly, the gamma class is a trimer found in bacteria and represents the most ancient carbonic anhydrase. These three classes of carbonic anhydrase enzymes lack sequence or structural similarities, but all share a conserved active site zinc atom (1).

Carbonic anhydrase IX (theoretical molecular weight 50kDa) belongs to the monomeric alpha class and is a single pass-transmembrane protein with two extracellular domains which serve catalytic and cell adhesion functions (2, 3). By cooperating with sodium bicarbonate cotransporters (NBC), lactate and proton exporting monocarboxylic acid transporters (MCT), and a sodium/hydrogen exchanger (NHE), carbonic anhydrase IX is involved in pH regulation across the cell membrane. This functional property protects cancer cells from intracellular acidification and partly explains the role of carbonic anhydrase IX in cancer cell survival and proliferation. In contrast, the pH regulating activity of carbonic anhydrase IX induces extracellular acidification, which has been implicated in epithelial to mesenchymal transition (EMT) and promoting cancer invasion. Carbonic anhydrase IX is frequently overexpressed in cancer cells (e.g., colorectal-, breast-, lung-carcinoma and brain tumors), an effect promoted by hypoxia within the tumor microenvironment (4). An exception are tumors carrying pVHL inactivating mutations, such as clear cell renal cell carcinoma (ccRCC), where HIF-alpha is stabilized due to dysfunctional proteasomal targeting and can induce HRE (Hypoxia Response Element) containing genes even under physiological normoxia (5). Carbonic anhydrase IX may be detected by immunostaining in tumors, which is found in association with necrotic tissue and metastatic cells. Because the expression of carbonic anhydrase IX correlates with both tumor grade and stage, analysis of its expression in tumors serves as a prognostic factor (4, 6).

Protocols

View specific protocols for Carbonic Anhydrase IX/CA9 Antibody - BSA Free (NB100-417):

Protocol for Flow Cytometry Intracellular Staining
Sample Preparation.
1. Grow cells to 60-85% confluency. Flow cytometry requires between 2 x 105 and 1 x 106 cells for optimal performance.
2. If cells are adherent, harvest gently by washing once with staining buffer and then scraping. Avoid using trypsin as this can disrupt certain epitopes of interest. If enzymatic harvest is required, use Accutase, Collagenase, or TrypLE Express for a less damaging option.
3. Reserve 100 uL for counting, then transfer cell volume into a 50 mL conical tube and centrifuge for 8 minutes at 400 RCF.
a. Count cells using a hemocytometer and a 1:1 trypan blue exclusion stain to determine cell viability before starting the flow protocol. If cells appear blue, do not proceed.
4. Re-suspend cells to a concentration of 1 x 106 cells/mL in staining buffer (NBP2-26247).
5. Aliquot out 100 uL samples in accordance with your experimental samples.

Tip: When cell surface and intracellular staining are required in the same sample, it is advisable that the cell surface staining be performed first since the fixation and permeablization steps might reduce the availability of surface antigens.

Intracellular Staining.
Tip: When performing intracellular staining, it is important to use appropriate fixation and permeabilization reagents based upon the target and its subcellular location. Generally, our Intracellular Flow Assay Kit (NBP2-29450) is a good place to start as it contains an optimized combination of reagents for intracellular staining as well as an inhibitor of intracellular protein transport (necessary if staining secreted proteins). Certain targets may require more gentle or transient permeabilization protocols such as the commonly employed methanol or saponin-based methods.
Protocol for Cytoplasmic Targets:
1. Fix the cells by adding 100 uL fixation solution (such as 4% PFA) to each sample for 10-15 minutes.
2. Permeabilize cells by adding 100 uL of a permeabization buffer to every 1 x 106 cells present in the sample. Mix well and incubate at room temperature for 15 minutes.
a. For cytoplasmic targets, use a gentle permeabilization solution such as 1X PBS + 0.5% Saponin or 1X PBS + 0.5% Tween-20.
b. To maintain the permeabilized state throughout your experiment, use staining buffer + 0.1% of the permeabilization reagent (i.e. 0.1% Tween-20 or 0.1% Saponin).
3. Following the 15 minute incubation, add 2 mL of the staining buffer + 0.1% permeabilizer to each sample.
4. Centrifuge for 1 minute at 400 RCF.
5. Discard supernatant and re-suspend in 100 uL of staining buffer + 0.1% permeabilizer.
6. Add appropriate amount of each antibody (eg. 1 test or 1 ug per sample, as experimentally determined).
7. Mix well and incubate at room temperature for 30 minutes- 1 hour. Gently mix samples every 10-15 minutes.
8. Following the primary/conjugate incubation, add 1-2 mL/sample of staining buffer +0.1% permeabilizer and centrifuge for 1 minute at 400 RCF.
9. Wash twice by re-suspending cells in staining buffer (2 mL for tubes or 200 uL for wells) and centrifuging at 400 RCF for 5 minutes. Discard supernatant.
10. Add appropriate amount of secondary antibody (as experimentally determined) to each sample.
11. Incubate at room temperature in dark for 20 minutes.
12. Add 1-2 mL of staining buffer and centrifuge at 400 RCF for 1 minute and discard supernatant.
13. Wash twice by re-suspending cells in staining buffer (2 mL for tubes or 200 uL for wells) and centrifuging at 400 RCF for 5 minutes. Discard supernatant.
14. Resuspend in an appropriate volume of staining buffer (usually 500 uL per sample) and proceed with analysis on your flow cytometer.

Immunocytochemistry Protocol

FAQs for Carbonic Anhydrase IX/CA9 Antibody - BSA Free

Showing  1 - 5 of 9 FAQs Showing All
  • Q: Could this antibody (CA9) be safely stored at -80C?

    A: The recommended storage temperature for NB100-417 is -20C. It may be possible to store this antibody at -80C, but this has not been confirmed by our lab. It is most important to ensure that that antibody does not undergo too many freeze-thaw cycles.

  • Q: Could you please let me know the immunogen peptide location for this Ab?

    A: The immunogen used to create this antibody was made to a cytoplasmic area of the protein.

  • Q: How many units do we need to purchase in order to stain 150 formalin fixed, paraffin embedded kidney biopsies? It depends on the amount used per slide, so could you please confirm how much antibody do you use per slide in IHC-P? Also, is the ab compatible with ENVISION FLEX+, HIGH pH, FOR AS?

    A: Unfortunately there is no number that I can provide to you as it is impossible to know for sure how many slides you will be able to stain with a vial. This will depend on your experimental conditions, your samples and how highly expressed the protein is, and what dilution you end up choosing. This antibody is recommended to be used at a 1:1000 dilution for IHC staining as this has worked well for our lab. You should order a single vial and test to determine what amount will be best for your assay rather than order too much or too little without first working with the antibody. As for your second question, that is not something that our lab has tested with so I am unsure if it is compatible or not. It has a fairly normal range pH in the buffer (7-8) so most likely the functions best around that range and not at a high pH.

  • Q: I am interested in using the CA9 antibody (NB100-417) that you supply. We dilute our antibodies in 5% milk TBS-Tween and usually freeze-thaw them multiple times. Is this possible with this antibody when diluted?

    A: I have checked with the lab and they have informed me that freezing is not recommended for NB100-417 under any circumstances. Unfortunately, the antibody would no longer be covered by our guarantee if it was stored at a temperature that did not match our storage instructions. Of course, you are free to test your proposed conditions if you would like, but we would not be able to accept responsibility if the antibody was damaged by this.

  • Q: I have a couple of questions regarding the Carbonic Anhydrase IX Antibody (NB100-417) listed on your website. We are wondering if this antibody is carrier-free, and if not, whether you have a carrier-free version?

    A: NB100-417 is carrier protein free but does contain 0.025% sodium azide. The buffer formulation is: PBS with 0.025% sodium azide. The following products are carrier protein and azide free (catalog numbers NBP2-34411, NBP2-34408, and NBP2-33152). If you would like to use NB100-417, we do offer antibody purification kits to remove unwanted buffer ingredients.

  • Q: I'm going to use your CA-9 Antibody for paraffin-Immunohistochemistry. Do I have to do any special pretreatments?

    A: We recommend antigen retrieval to ensure the epitope is not masked, and we also recommend that you add a permeablizing agent to access the epitope in the nucleus. A protocol specific for this product can be found under Product PDFs, labelled as "IHC Protocol". 

  • Q: Is this antibody is carrier-free? If not, do you have a carrier-free version?

    A: NB100-417 is carrier protein free, but does contain 0.1% sodium azide. The buffer formulation is: Tris-citrate/phosphate, pH 7-8 with 0.1% sodium azide. The following products are carrier protein and azide free (catalog numbers 23300002, H00000768-B01P and H00000768-D01P). If you would like to use NB100-417, we do offer antibody purification kits to remove unwanted buffer ingredients. See this link here for those products.

  • Q: What is the predicted theoretical molecular weight of Carbonic Anhydrase IX/CA9 antibodies?

    A: The TMW for Carbonic Anhydrase IX/CA9 antibodies is 50 kDa. Please note the observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

  • Q: Could this antibody (CA9) be safely stored at -80C?

    A: The recommended storage temperature for NB100-417 is -20C. It may be possible to store this antibody at -80C, but this has not been confirmed by our lab. It is most important to ensure that that antibody does not undergo too many freeze-thaw cycles.

  • Q: Could you please let me know the immunogen peptide location for this Ab?

    A: The immunogen used to create this antibody was made to a cytoplasmic area of the protein.

  • Q: How many units do we need to purchase in order to stain 150 formalin fixed, paraffin embedded kidney biopsies? It depends on the amount used per slide, so could you please confirm how much antibody do you use per slide in IHC-P? Also, is the ab compatible with ENVISION FLEX+, HIGH pH, FOR AS?

    A: Unfortunately there is no number that I can provide to you as it is impossible to know for sure how many slides you will be able to stain with a vial. This will depend on your experimental conditions, your samples and how highly expressed the protein is, and what dilution you end up choosing. This antibody is recommended to be used at a 1:1000 dilution for IHC staining as this has worked well for our lab. You should order a single vial and test to determine what amount will be best for your assay rather than order too much or too little without first working with the antibody. As for your second question, that is not something that our lab has tested with so I am unsure if it is compatible or not.

Unfortunately, the antibody would no longer be covered by our guarantee if it was stored at a temperature that did not match our storage instructions. Of course, you are free to test your proposed conditions if you would like, but we would not be able to accept responsibility if the antibody was damaged by this.

  • Q: What is the predicted theoretical molecular weight of Carbonic Anhydrase IX/CA9 antibodies?

    A: The TMW for Carbonic Anhydrase IX/CA9 antibodies is 50 kDa. Please note the observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.

  • Q: Could this antibody (CA9) be safely stored at -80C?

    A: The recommended storage temperature for NB100-417 is -20C. It may be possible to store this antibody at -80C, but this has not been confirmed by our lab. It is most important to ensure that that antibody does not undergo too many freeze-thaw cycles.

  • Q: Could you please let me know the immunogen peptide location for this Ab?

    A: The immunogen used to create this antibody was made to a cytoplasmic area of the protein.

  • Q: How many units do we need to purchase in order to stain 150 formalin fixed, paraffin embedded kidney biopsies? It depends on the amount used per slide, so could you please confirm how much antibody do you use per slide in IHC-P? Also, is the ab compatible with ENVISION FLEX+, HIGH pH, FOR AS?

    A: Unfortunately there is no number that I can provide to you as it is impossible to know for sure how many slides you will be able to stain with a vial. This will depend on your experimental conditions, your samples and how highly expressed the protein is, and what dilution you end up choosing. This antibody is recommended to be used at a 1:1000 dilution for IHC staining as this has worked well for our lab. You should order a single vial and test to determine what amount will be best for your assay rather than order too much or too little without first working with the antibody. As for your second question, that is not something that our lab has tested with so I am unsure if it is compatible or not. It has a fairly normal range pH in the buffer (7-8) so most likely the functions best around that range and not at a high pH.

  • Q: I am interested in using the CA9 antibody (NB100-417) that you supply. We dilute our antibodies in 5% milk TBS-Tween and usually freeze-thaw them multiple times. Is this possible with this antibody when diluted?

    A: I have checked with the lab and they have informed me that freezing is not recommended for NB100-417 under any circumstances. Unfortunately, the antibody would no longer be covered by our guarantee if it was stored at a temperature that did not match our storage instructions. Of course, you are free to test your proposed conditions if you would like, but we would not be able to accept responsibility if the antibody was damaged by this.

  • Q: I have a couple of questions regarding the Carbonic Anhydrase IX Antibody (NB100-417) listed on your website. We are wondering if this antibody is carrier-free, and if not, whether you have a carrier-free version?

    A: NB100-417 is carrier protein free but does contain 0.025% sodium azide. The buffer formulation is: PBS with 0.025% sodium azide. The following products are carrier protein and azide free (catalog numbers NBP2-34411, NBP2-34408, and NBP2-33152). If you would like to use NB100-417, we do offer antibody purification kits to remove unwanted buffer ingredients.

  • Q: I'm going to use your CA-9 Antibody for paraffin-Immunohistochemistry. Do I have to do any special pretreatments?

    A: We recommend antigen retrieval to ensure the epitope is not masked, and we also recommend that you add a permeablizing agent to access the epitope in the nucleus. A protocol specific for this product can be found under Product PDFs, labelled as "IHC Protocol". 

  • Q: Is this antibody is carrier-free? If not, do you have a carrier-free version?

    A: NB100-417 is carrier protein free, but does contain 0.1% sodium azide. The buffer formulation is: Tris-citrate/phosphate, pH 7-8 with 0.1% sodium azide. The following products are carrier protein and azide free (catalog numbers 23300002, H00000768-B01P and H00000768-D01P). If you would like to use NB100-417, we do offer antibody purification kits to remove unwanted buffer ingredients. See this link here for those products.
