synthetic peptide corresponding to an internal sequence of human β-Defensin 3.


Anti-β-Defensin 3 antibody produced in rabbit is suitable for immunoblotting at a working dilution of 1:500 to 1:1000 and for immunohistochemistry at 1:2 dilution. It was used for a quantitative immunohistochemical study of HBD-3 on skin lesions from patients having Kaposi’s sarcoma in a study. It was used as a primary antibody for western blot analysis of oral mucosa and extraoral skin samples to study the quantitative comparison of the expression of antimicrobial peptides.

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.

Target description

β-Defensin 3 encodes defensin, beta 103B, which has broad spectrum antimicrobial activity and may play an important role in innate epithelial defense.

Physical form

solution in phosphate buffered saline, containing 0.02% sodium azide.
