Anti-CST3 Antibody

This Rabbit polyclonal antibody from Antibodies.com targets human CST3 (Cystatin C), a roughly 13 kDa cysteine protease inhibitor encoded by the CST3 gene and expressed broadly across tissues. Cystatin C is widely studied as a biomarker of glomerular filtration rate and is implicated in hereditary cerebral amyloid angiopathy when its coding sequence carries specific mutations, so reliable detection in tissue sections and protein lysates is useful in both renal and neurodegeneration research.

The antibody is supplied as 100 µl of unconjugated antiserum in a vial, raised in rabbit, and validated for Western blot and immunohistochemistry on human samples. The polyclonal format recognizes multiple epitopes on Cystatin C, which can improve signal in IHC where the antigen may be partially masked by fixation. Aliquot on receipt and store at -20 °C, avoiding repeated freeze-thaw cycles to preserve activity for downstream immunodetection workflows.
