Verotoxin I-B subunit (Shiga-like, SLT-1b)

Verotoxins are also called Shiga-like toxins (SLTs). Enterohemorrhagic Escherichia coli (EHEC) strains which are primarily of serotypes 0157:H7, 026:H11 and O111:H8 have been incriminated as etiologic agents of hemorrhagic colitis and Hemolytic-uremic syndrome, a generalized disease characterized by acute renal failure, thrombocytopenia and microangiopathic hemolytic anemia. There are several distinct E.coli SLTs. SLT-I and SLT-II are produced by EHEC. SLT-I and Shiga toxin share > 99% deduced amino acid sequence homology, whereas SLT-I and SLT-II share about 60% deduced amino acid sequence homology. SLT-I and SLT-II are antigenically distinct. The protein structure of the toxin consists of two domains: the A polypeptide that inhibits protein synthesis by targeting ribosomes, and the B polypeptide pentamer that binds to the eukaryotic cell receptor globotriaosylceramide (Gb3) leading to receptor-mediated endocytosis. \n\nApplications:\nSuitable for use in Western Blot, ELISA and Inhibition. Other applications not tested.\n\nRecommended Dilution:\nWestern Blot: 1:10\nInhibition: in vitro dilutions should be made according to the amount of toxin to be inactiviated.\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20 degrees C. Aliquots are stable for at least 12 months. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
