They are 2-6 k Da proteins and take important roles in innate immune system. On the basis of their size and pattern of disulfide bonding, mammalian defensins are classified into alpha, beta and theta categories. β-Defensins contain a six-cysteine motif that forms three intra-molecular disulfide bonds. Four human β-defensins have been identified and they are expressed on some leukocytes and at epithelial surfaces. Because β-defensins is cationic peptides, they can therefore interact with the membrane of invading microbes, which are negative due to lipopolysaccharides (LPS) and lipoteichoic acid (LTA) found in the cell membrane. Especially, they have higher affinity to the binding site compared to Ca2+ and Mg2+ ions. Furthermore, they can affect the stability of the membrane.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eResearch_area\u003c\/b\u003e:Immunology\u003c\/p\u003e\u003cp\u003e\u003cb\u003ePurity\u003c\/b\u003e:\u0026gt; 95 % by SDS-PAGE and HPLC analyses.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eSource\u003c\/b\u003e:Escherichia coli.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFull product name\u003c\/b\u003e:Recombinant Mouse Beta-defensin 3\u003c\/p\u003e\u003cp\u003e\u003cb\u003eBiological activity\u003c\/b\u003e:Fully biologically active when compared to standard.
