产品信息

背景说明： Defensins are cationic peptides.It is an important ingredient of the innate immune system.β-defensins are expressed on some leukocytes and epithelial surfaces.Four human β-Defensins have been identified to date: BD-1，BD-2，BD-3 and BD-4.β-defensins contain a six-cysteine motif，they forms three intra-molecular disulfide bonds.β-defensins are also chemoattractant towards immature dendritic cells and memory T cells.The β-defensin proteins are expressed as the C-terminal portion of precursors; they are released by proteolytic cleavage of a signal sequence.
