Anti-WAP13 antibodies enable researchers to detect and measure the WAP13 antigen in biological samples. This target is a reported synonym of the WFDC13 gene, which encodes WAP four-disulfide core domain 13. This protein is known to function in innate immune responses, among other biological roles. The human version of WAP13 has a canonical amino acid length of 93 residues and a protein mass of 10.4 kilodaltons. It is reported to be a secreted protein.
