Anti-WAP8 antibodies enable researchers to detect and measure the WAP8 antigen in biological samples. This target is a reported synonym of the WFDC8 gene, which encodes WAP four-disulfide core domain 8. The human version of WAP8 has a canonical amino acid length of 241 residues and a protein mass of 27.8 kilodaltons. It is reported to be a secreted protein that is notably expressed in the epididymis.
