Anti-Cystatin-C Antibody

The polyclonal reagent from Antibodies.com targets Cystatin-C, a 13 kDa cysteine protease inhibitor encoded by the CST3 gene and constitutively secreted by all nucleated human cells. This unconjugated Rabbit polyclonal antibody is validated for Western blot (WB) and immunohistochemistry (IHC) applications and specifically detects the human target in tissue lysates and fixed sections.

Cystatin-C is widely investigated as a serum biomarker of glomerular filtration rate, where it outperforms creatinine in flagging subtle declines in renal function, and has been examined in research on cerebral amyloid angiopathy, neurodegeneration, and cardiovascular risk stratification. Supplied as 100 µg in a vial, the antibody supports studies of extracellular protease regulation and tubular physiology. For best results, store at -20 °C and aliquot to limit freeze-thaw cycles. Intended for research use only; not for diagnostic or therapeutic use.
