Clone Number: EBS-I-100
Immunogen: C.difficile toxin A
Concentration: 100 ug/ml
Storage buffer: PBS with 0.02% sodium azide
Additional info: EBS-I-100 reacts with C. difficile Toxin A, but not with V. cholerae subunit a, V. cholerae toxin, Pseudomonas aeruginosa exotoxin A, H-LT, P-LT. C. difficile is a major nosocomial pathogen that causes antibiotic-associated colitis and mediates inflammatory diarrhea by releasing two large protein enterotoxins (toxin A and toxin B) that are able to disrupt intestinal epithelial cells via their transferase activity and ability to monoglucosylate members of the Rho family. C. difficile toxin A is a toxin that is composed of 39 repeats that are responsible for binding to intestinal epithelial cell surface carbohydrates. C. difficile toxin A causes significant apoptosis of colonocytes which contributes to the formation of ulcers and pseudo-membranes in a pathway that involves p38-dependent activation of p53 and induction of p21, leading to cytochrome c release and caspase-3 activation through Bak activation.
