Anti-Cystatin C Antibody

This rabbit polyclonal reagent from Antibodies.com targets human Cystatin C, a secreted cysteine protease inhibitor of roughly 13 kDa that circulates in plasma and is widely studied as a biomarker of glomerular filtration and kidney function. The unconjugated antibody is supplied at 1 mg/ml in phosphate buffered saline containing 0.05% sodium azide at approximately pH 7.2, and is validated for western blot and immunohistochemistry workflows against human samples. Researchers use it to probe Cystatin C expression in tissues and cell lysates relevant to renal physiology, neurodegeneration studies such as cerebral amyloid angiopathy, and cardiovascular risk investigations where serum Cystatin C levels correlate with renal impairment. Each vial contains 100 µl of antibody reagent, which can be aliquoted to limit freeze-thaw cycles, and the polyclonal format provides recognition of multiple epitopes on the Cystatin C target for robust signal in detection assays.
