Anti-DEFB121 Antibody

DEFB121 (beta-defensin 121) is a member of the defensin family of antimicrobial peptides, which play established roles in innate immune defense against microbial pathogens. This unconjugated rabbit polyclonal antibody from Antibodies.com is raised against the human DEFB121 protein and is validated for use in Western blot (WB) and immunohistochemistry (IHC) workflows. The reagent is supplied at 1 mg/ml in a PBS buffer containing 0.1% sodium azide and 50% glycerol, with a total volume of 100 µl per vial. Recommended storage is at -20 °C in aliquots to limit cycle degradation, with avoidance of repeated freeze-thaw events. The antibody recognizes human DEFB121 and is appropriate for researchers investigating defensin biology, mucosal immunity, or reproductive tract antimicrobial peptide expression, since DEFB121 has been detected in epididymal and testicular tissue in published expression studies. As an unconjugated primary reagent, it offers flexibility for downstream labeling with fluorophores, enzymes, or biotin depending on experimental design, and works in chromogenic IHC on fixed tissue sections as well as standard immunoblotting of cell or tissue lysates.
