Anti-Cystatin C Antibody

The Antibodies.com Anti-Cystatin C Antibody is a rabbit polyclonal IgG reagent supplied as 100 µg of liquid, validated for Western blot detection of human Cystatin C. Cystatin C is a 13 kDa cysteine protease inhibitor encoded by the CST3 gene and constitutively secreted by all nucleated cells, with serum levels widely used as a biomarker for glomerular filtration rate in renal function studies. This unconjugated primary antibody supports chemiluminescent visualization of endogenous Cystatin C in cell lysates, tissue homogenates, and urine samples, and has been referenced in research on neurodegeneration, cardiovascular risk stratification, and diabetic nephropathy. The reagent is shipped frozen and should be stored at -20 °C, with single-use aliquoting recommended to limit freeze-thaw cycles and preserve binding activity over the product shelf life. Intended for research use only.
