These protease, serine, 57 ELISA kits are immunodetection tools for measuring specific protein levels in biological samples. protease, serine, 57 is an alias of the human PRSS57 gene, which encodes the protein, serine protease 57. Notably, protease, serine, 57 is known to play a role in proteolysis, among other functions. The PRSS57 protein is described to be 283 amino acid residues in length and 30.3 kilodaltons in mass. Its subcellular localization is in the cytoplasm and is secreted. In terms of tissue specificity, it is notably expressed in peripheral blood neutrophil granulocytes, but not in other types of leukocytes. This protein is known to be N-glycosylated and cleaved. Other names for this target antigen include neutrophil serine protease 4 and protease, serine 57.
