Verotoxin 1

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 micro- angiopathic 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.

Applications
Suitable for use in Western Blot, ELISA and Inhibition. Other applications not tested.
Recommended Dilution
Western Blot: 1:10 Inhibition: in vitro dilutions should be made according to the amount of toxin to be inactiviated. Optimal dilutions to be determined by the researcher.
Storage and Stability

Form
Supplied as a liquid in PBS, 0.1% BSA.
Purity
Purified by Protein G affinity chromatography
Specificity
Recognizes the 1-B subunit of Verotoxin (Shiga-like toxin-1).
