Human Cystatin 2 (CST2) ELISA Kit

CST2 (Cystatin 2) is a secreted cysteine protease inhibitor belonging to the type 2 cystatin family, with documented roles in oral biology, salivary proteomics, and head and neck cancer research. The Assay Genie Human Cystatin 2 (CST2) ELISA Kit supports quantitative measurement of CST2 protein in tissue homogenates, cell lysates, and cell culture supernatants derived from human samples.

Altered salivary and tissue cystatin concentrations have been associated with squamous cell carcinoma progression, inflammatory responses, and remodeling of the tumor microenvironment. Researchers investigating these biomarkers, saliva proteomics, and protease-antiprotease balance use the kit to monitor CST2 levels in in vitro cell culture and tissue-based experiments.

Supplied as a complete reagent set configured for 96 assays in a microplate format, the kit is intended for research use only. Components should be stored refrigerated at standard short-term temperatures and protected from light to preserve antibody binding activity through the kit's stated shelf life.
