Anti-NSP4 antibodies enable researchers to detect and measure the NSP4 antigen in biological samples. This target is a reported synonym of the PRSS57 gene, which encodes serine protease 57. This protein is known to function in proteolysis, among other biological roles. The human version of NSP4 has a canonical amino acid length of 283 residues and a protein mass of 30.3 kilodaltons. It is reported to be localized in the cytoplasm and is secreted of cells. NSP4 is a member of the Peptidase S1 protein family. Indicated applications for NSP4 antibodies listed below include ELISA and Western Blot.
