Cystatin C is a secreted cysteine protease inhibitor that inhibits Cathepsins B, H, K, L, and S. Cystatin C serum concentration correlates closely to the glomerular filtration rate (GFR); elevated levels are associated with coronary artery and cardiovascular disease risk. Dysregulation of Cystatin C can modulate tumor growth and metastasis. In humans, the L68Q variant forms dimers and oligomers more easily than wild type protein and is the cause for hereditary Cystatin C amyloid angiopathy.

Product Summary for Mouse/Rat Cystatin C Quantikine ELISA Kit
The Quantikine Mouse/Rat Cystatin C Immunoassay is a 4.5 hour solid phase ELISA designed to measure mouse and rat Cystatin C in cell culture supernates, cell lysates, serum, plasma, and urine. It contains NS0-expressed recombinant mouse Cystatin C and antibodies raised against the recombinant factor. This immunoassay has been shown to quantitate the recombinant factor accurately. Results obtained using natural mouse or rat Cystatin C 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 and rat Cystatin C.

Protocols
View specific protocols for Mouse/Rat Cystatin C Quantikine ELISA Kit (MSCTC0):
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.
- Prepare all reagents, standard dilutions, and samples as directed in the product insert.
- Remove excess microplate strips from the plate frame, return them to the foil pouch containing the desiccant pack, and reseal.
- Add 50 µL of Assay Diluent to each well.
- Add 50 µL of Standard, control, or sample to each well. Cover with a plate sealer, and incubate at room temperature for 2 hours.
- Aspirate each well and wash, repeating the process 4 times for a total of 5 washes.
- Add 100 µL of Conjugate to each well. Cover with a new plate sealer, and incubate at room temperature for 2 hours.
- Aspirate and wash 5 times.
- Add 100 µL Substrate Solution to each well. Incubate at room temperature for 30 minutes. PROTECT FROM LIGHT.
- Add 100 µL of Stop Solution to each well. Read at 450 nm within 30 minutes. Set wavelength correction to 540 nm or 570 nm.
