Anti-DEFB109P1B antibodies enable researchers to detect and measure the DEFB109P1B antigen in biological samples. This target is a reported synonym of the DEFB109B gene, which encodes defensin beta 109B. This protein is reported to exhibit antibacterial activity. The human version of DEFB109P1B has a canonical amino acid length of 87 residues and a protein mass of 9.9 kilodaltons. It is reported to be a secreted protein. DEFB109P1B is a member of the Beta-defensin protein family.
