These PYY-I ELISA kits are immunodetection tools for measuring the levels of PYY-I in biological samples. PYY-I is an alias of the human PYY gene, which encodes the protein, peptide YY. Notably, PYY-I is known to play a role in intestinal epithelial cell differentiation, among other functions. The PYY protein is 97 amino acid residues in length and 11.1 kilodaltons in mass. However, as many as 2 protein isoforms have been identified. It is known to be a secreted protein. This protein is known to be cleaved. Other names for this target antigen include PYY-I.
