Anti-MEPI antibodies enable researchers to detect and measure the MEPI antigen in biological samples. This target is a reported synonym of the SERPINI2 gene, which encodes serpin family I member 2. The human version of MEPI has a canonical amino acid length of 405 residues and a protein mass of 46.1 kilodaltons. It is reported to be a secreted protein. Other names for this target antigen include PANCPIN and PI14.
