Anti-hBD-29 antibodies enable researchers to detect and measure the hBD-29 antigen in biological samples. This target is a reported synonym of the DEFB129 gene, which encodes defensin beta 129. This protein is reported to exhibit antibacterial activity. The human version of hBD-29 has a canonical amino acid length of 183 residues and a protein mass of 20.3 kilodaltons. It is reported to be a secreted protein that is notably expressed in the epididymis. hBD-29 is a member of the Beta-defensin protein family.
