Anti-CAPN4 antibodies enable researchers to detect and measure the CAPN4 antigen in biological samples. This target is a reported synonym of the CAPNS1 gene, which encodes calpain small subunit 1. This protein is known to function in the regulation of cell proliferation and proteolysis, among other biological roles. The human version of CAPN4 has a canonical amino acid length of 268 residues and a protein mass of 28.3 kilodaltons. It is reported to be localized in the cell membrane and cytoplasm of cells and widely expressed in many tissue types. Other names for this target antigen include CALPAIN4, CALPAIN4, and CANP. Indicated applications for CAPN4 antibodies listed below include ELISA, Western Blot, and Immunohistochemistry.
