Product Summary for Mouse IL-6R alpha Quantikine ELISA Kit

The Quantikine Mouse IL-6 R alpha Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse IL-6 R alpha levels in cell culture supernates, serum, and heparin plasma. It contains NS0-expressed recombinant mouse IL-6 R alpha and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant mouse IL-6 R alpha accurately. Results obtained using natural mouse IL-6 R alpha showed dose-response curves that were parallel to the standard curves obtained using the recombinant kit standards. These results indicate that this kit can be used to determine relative mass values for natural mouse IL-6 R alpha.

Background: IL-6R alpha

IL-6R alpha is a transmembrane subunit of the receptor for Interleukin-6. It associates with gp130 which is a shared component of the receptors for CLC, CNTF, CT-1, IL-11, IL-27, LIF, and OSM. Soluble forms of IL-6R alpha are generated by both alternative splicing and proteolytic cleavage. In a mechanism known as trans-signaling, complexes of soluble IL-6 and IL-6R alpha elicit responses from gp130-expressing cells that lack cell surface IL-6R alpha. IL-6 plays important roles in the acute phase reaction, inflammation, hematopoiesis, bone metabolism, and cancer progression. IL-6, along with TNF-alpha and IL-1, drives the acute inflammatory response and the transition from acute inflammation to either acquired immunity or chronic inflammatory disease. When dysregulated, it contributes to chronic inflammation in obesity, insulin resistance, inflammatory bowel disease, arthritis, sepsis, and atherosclerosis.

Protocols

View specific protocols for Mouse IL-6R alpha Quantikine ELISA Kit (MR600):

Refer to the product for complete assay procedure.

Bring all reagents and samples to room temperature before use. It is recommended that all samples, standards, and controls be assayed in duplicate.
  1.   Prepare all reagents, standard dilutions, and samples as directed in the product insert.
  2.   Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
    3. 50 µL Assay Diluent
  3.   Add 50 µL of Assay Diluent to each well.
    4. 50 µL Standard, Control, or Sample
  4.   Add 50 µL of Standard, Control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours on a horizontal orbital microplate shaker.
  5.   Aspirate each well and wash, repeating the process 3 times for a total of 4 washes.
    6. 100 µL Conjugate
  6.   Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours on the shaker.
  7.   Aspirate and wash 4 times.
    8. 100 µL Substrate Solution
  8.   Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes on the benchtop. PROTECT FROM LIGHT.
    9. 100 µL Stop Solution

Showing  1 - 1 of 1 FAQ Showing All

  • Q: Assay Diluent RD1-14 contains visible precipitate. Is this acceptable to use?

    A: A small amount of precipitate is expected and acceptable in Assay Diluent RD1-14. Variability has been observed between vials and diluent lots. It may not fully resolubilize but this will not impact assay performance. It is not recommended to filter the precipitate.
