General description

Beta Defensin-3 is a novel 5 kDa nonhemolytic antimicrobial protein peptide which may be important in the innate epithelial defense of infections by various microorganisms seen in skin and lung (such as cystic fibrosis).


Recognizes the 5-6 kDa human Defensin-3, beta protein.


A synthetic peptide consisting of amino acids 23-33 [GIINTLQKYYC] of the human beta-defensin-3 protein.


Anti-Defensin Antibody, β3 is an antibody against Defensin for use in ELISA & WB.

Western blotting: Tricine-SDS- PAGE gels recommended: 1:500-1:1,000, migrates as a 5-6kDa band; Tricine-SDS-urea PAGE gels: Native Beta Defensin 3 migrates as a 9kDa band; the larger size is because of the reduction of the three cysteine bridges present in the peptide protein

Optimal working dilutions must be determined by the end user.
