Recombinant Human Defensin, Beta 4A

Cat. No.: DEFB4A-5190H
Product Overview: Recombinant Human DEFB4Ais a protein containing 41 amino acid residues. DEFB4A is expressed in E. coli, MW 4.3kDa.
Description: Beta-defensin 2(DEFB4A) also known as skin-antimicrobial peptide 1 (SAP1) is a peptide thatin humans is encoded by the DEFB4A (defensin, beta 4) gene. Humanbeta-defensin-2 (DEFB4A) is a cysteine-rich cationic low molecular weightantimicrobial peptide recently discovered in lesional skin.
Source: Human
Host: E. coli
Form: Sterile filtered andlyophilized with no additives.
Purity: >98% by SDS-PAGEanalyses.
Molecular Weight: 4.3 kDa
Biological Activity: Determined by itsability to chemoattract immature dendritic cells using a concentration rangeof 10.0-100.0 ng/ml.
