Anti-CST1 Antibody

This polyclonal antibody from Antibodies.com targets human Cystatin SN (CST1), a secreted cysteine protease inhibitor expressed in saliva, tears, and epithelial tissues. Raised in rabbit and purified as an IgG fraction, the unconjugated reagent is supplied in a single-use vial at 1 mg/ml in 100 µl of phosphate buffered saline (PBS) containing 15 mM sodium azide at approximately pH 7.2, ready for dilution into standard western blot workflows. The antibody recognizes CST1 in human, mouse, and rat samples, supporting comparative studies of cystatin family expression across model systems and disease models where CST1 has been implicated, including gastric, colorectal, and pancreatic cancer research. The buffered formulation supports refrigerated storage with appropriate aliquoting to limit freeze-thaw cycles and preserve binding activity over multiple experiments. Researchers investigating salivary gland biology, mucosal immunity, or cysteine protease regulation can deploy it for western blot detection of endogenous CST1 levels in cell lysates and tissue homogenates.
