Anti-TMPRSS1 antibodies enable researchers to detect and measure the TMPRSS1 antigen in biological samples. This target is a reported synonym of the HPN gene, which encodes hepsin. This protein is known to function in the regulation of apoptosis, among other biological roles. The human version of TMPRSS1 has a canonical amino acid length of 417 residues and a protein mass of 45 kilodaltons. It is reported to be localized in the cell membrane of cells and widely expressed in many tissue types. TMPRSS1 is a member of the Peptidase S1 protein family. Indicated applications for TMPRSS1 antibodies listed below include ELISA and Western Blot.
