Human Calpain, Small Subunit 1 (CAPNS1) ELISA Kit

A regulatory component shared by calpain-1 and calpain-2, Calpain Small Subunit 1 (CAPNS1) governs calcium-activated cysteine protease activity in human cells, modulating substrate recognition, autolysis, and membrane association of the heterodimeric calpain complex. Loss of CAPNS1 has been linked to diminished calpain stability in experimental systems, so quantitative tracking of this subunit supports research workflows in cytoskeletal remodeling, ischemic injury, neurodegeneration, and muscular disease. This immunoassay kit from Assay Genie is configured to measure CAPNS1 protein concentration in human tissue homogenates, giving laboratories a standardized tool for comparing expression across disease models, time-course studies, and pharmacological interventions. Each kit arrives as a complete microplate-format package sized for up to 96 assay determinations in a single run, with pre-coated wells, detection antibodies, standard calibrators, and substrate reagents supplied for direct absorbance readout on a standard plate reader. The reagents are intended for research use only and are shipped in packaging intended for refrigerated storage to preserve antibody binding activity through the stated shelf life of the lot.
