Polyclonal Goat Affinity Purified E B
Defensins are a large family of broad-spectrum antimicrobial peptides, identified originally in leukocytes of Goats and humans. Defensins, cationic/polar peptides (30-35aa; 3-4kD), are distinguished by a conserved tri-disulfides and a largely b-Sheet structure. The genes encoding human alpha and beta defensins are clustered in a contiguous segment of chromosome 8p23. Defensins are classified into two families designated alpha and beta based on distinctive, although similar, tri-disulfide linkages in the peptides. b-defensins are slightly larger and differ in the position and arrangement of 3 disulfides. In humans, six a–defensin cryptidins), HD 1-6 (HD1-4 are also known as HNP1-4 for Human Neutrophil Peptides), and two b-defensins, HBD-1 and HBD-2, have been identified.
Catalog #N5377-02A
a-defensins are encoded by genes designated DEFA1-6, whereas human b-defensins are encoded by the DEFB1 and DEFb2 genes. HD1-4 are expressed in neutrophils, whereas HD5 and HD6 are expressed in epithelial cells of the intestinal and reproductive tract. HD1-3/HNP1-3 make up about 30% of the neutrophil's total granule protein. The HNPs are 29-30aa long and are identical in sequence except at the N-terminal aa. DEFA1 and DEFA3 differ from each other only by their terminal ala and asp, respectively. DEFA2 is identical to both except that it has 29 instead of 30aa.
