Human Cystatin 1 (CST1) ELISA Kit

Cystatin 1 (CST1), also referred to as Cystatin SN, is a secreted cysteine protease inhibitor belonging to the type 2 cystatin family. Research has linked altered CST1 expression to several malignancies, including gastric, colorectal, and pancreatic cancers, making it a subject of active investigation in oncology and biomarker discovery. This Assay Genie kit supports the quantitative measurement of CST1 in human samples and is compatible with workflows involving tissue homogenates, cell lysates, cell culture supernatants, and serum or plasma specimens. The 96-assay format is intended for research use only and provides investigators with a reproducible tool for studies exploring cysteine protease inhibitor biology, tumour microenvironment signalling, and candidate diagnostic or prognostic markers. Each kit contains the reagents required to run a standard ELISA workflow, with absorbance readings captured on a conventional microplate reader. The assay is for research use only and is not intended for diagnostic or clinical applications.
