Anti-defensin beta 126 antibodies are used for the immunodetection of the protein encoded by the DEFB126 gene. In humans, the canonical protein has a reported length of 111 amino acid residues and a mass of 12.2 kDa. It is known to be a secreted protein. It is reported to have high-level and epididymis-specific expression. A member of the Beta-defensin protein family, it is known to be involved with innate immune responses. Post-translational modifications have been described, including O-glycosylation. Other names for this target antigen include epididymal secretory protein ESP13.2, epididymis secretory sperm binding protein, and beta-defensin 126. Gene orthologs have been identified in the mouse, rat and chimpanzee species. ELISA is a widely used application for the defensin beta 126 antibodies listed below. In addition, Western Blot is also a common application.
