Beta-Defensin-1 (MBD-1)

Catalogue number: MBD011-S

Units100 µl
Application ELISA
IHC not established
The peptide fragment of MBD-1 used for immunisation shows 87% sequence homology rat beta-defensin-1 but no homology to other known defensins. Mammalian defensins are Cys-rich antimicrobial peptides which specifically react against Gram-negative bacteria. Originally defensins were isolated from hemolysates, but they can also be found on the cell surface of epithelia of the urogenital tract, lung, and trachea. In leukocytes defensins are stored in granules being released into phagolysosomes for the destruction of incorporated microorganisms. Amino acid sequences of alpha-defensins 1-4 (HNP1-4) and beta-Defensins 1-4 (HBD1-4) are known. Beta-defensin-1 and beta-defensin-2 share 34% amino acid sequence homology. Mouse beta-defensin-11 (MBD-1), cross-reactivity with rat expected, no cross-reaction with HBD-1.
