Human Cystatin SN PharmaGenie ELISA Kit (SBRS0481)

Cystatin SN (gene symbol CST1) is a secreted type-2 cysteine protease inhibitor that has attracted interest in studies of oral mucosal biology, salivary proteomics, and several cancer models in which its expression is dysregulated. This quantitative immunoassay from Assay Genie provides a tool for measuring CST1 protein levels in research samples, supporting investigations into biomarker discovery and target validation workflows.

Configured as a 96 assays-format kit with a pre-coated plate, the assay is validated for use with human samples including cell culture supernatant, plasma, and serum specimens. Reagents are intended for research use only and should be handled according to the accompanying insert. Allow kit components to equilibrate before initiating the protocol, and store reagents refrigerated between runs to preserve activity.

As part of the Assay Genie PharmaGenie product family, the kit fits into drug discovery, biopharmaceutical development, and translational research pipelines where reproducible quantification of human proteins is required. The standard curve and detection reagents support colorimetric readout on standard laboratory microplate readers, making the workflow accessible for laboratories already running plate-based immunoassays.
