A non-glycosylated secreted protein and member of the type 2 cystatin superfamily, which acts as a potent inhibitor of both endogenous and pathogenic cysteine proteinases. Cystatin C is produced by nucleated cells and is present in a variety of biological fluids. Changes in cystatin C
have been associated with a number of cardiovascular diseases, including atherosclerosis and myocardial infarction, and measurement of plasma cystatin C levels can be used as a more sensitive marker than creatinine for determining glomerular filtration rate (GFR) in the kidneys.
Applications:
Suitable for use in ELISA. Other applications not tested.
Recommended Dilution:
Optimal dilutions to be determined by the researcher.
Storage and Stability:
May be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
