Anti-Cystatin A Antibody

Offered through Antibodies.com, this rabbit polyclonal reagent is raised against Cystatin A (CSTA), a small intracellular cysteine protease inhibitor also known as Stefin A. It is supplied as 50 µl of liquid at approximately 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol, and is unconjugated, allowing users to apply their own detection chemistry. The antibody is purified to an estimated purity of greater than 95% and is certified for Research Use Only. Recommended applications are Western Blot (WB) and ImmunoHistoChemistry (IHC), and the reagent has been validated for reactivity with human samples. Polyclonal clonality in a rabbit host typically corresponds to IgG as the isotype, making it suitable for routine immunodetection workflows. For best preservation of activity, the product should be stored according to standard frozen antibody conditions (typically -20 °C), avoiding repeated freeze–thaw cycles. The listed supplier code is A30238 (50 µl size), and the product is distributed via AFMS to laboratories working on skin barrier biology, inflammatory skin disease, and protease/anti-protease balance research, where Cystatin A serves as a relevant marker.
