Anti-Cystatin B Antibody

Cystatin B (Stefin B) is a cytoplasmic cysteine cathepsin inhibitor implicated in Unverricht–Lundborg progressive myoclonic epilepsy, tumor invasion biology, and oxidative stress signaling. This unconjugated rabbit polyclonal reagent from Antibodies.com recognizes endogenous Cystatin B in human and rat samples and is validated for western blot, immunohistochemistry, immunofluorescence, and ELISA workflows. Provided as 100 µl of polyclonal antiserum, it accommodates multiple membranes, slide batches, or microplate wells from a single shipment. Investigators working on neurodegeneration, epithelial-mesenchymal transition, or protease–antiprotease balance use Stefin B detection to profile tissue expression, validate cell line models, and complement cathepsin co-staining experiments.
