Cat.No.
ECs2973-265S
Species
Shiga Like Toxin
Product Name
Recombinant Shiga Like Toxin ECs2973 protein, His-tagged
Product Overview
Recombinant Shiga Like Toxin-1 Subunit B from E.Coli O157:H7 produced in E.coli containing amino acids 2-90 of the Shiga Like Toxin-1 Subunit B. The Shiga Like Toxin 1 protein is fused to a 6xHis tag at its N-terminus and purified by proprietary chromatographic technique.
Description
Shiga-like toxin (verotoxin) is a toxin produced by some strains of E. coli Shiga-like toxin is named for its similarity to the AB5-type Shiga toxin produced by the bacteria Shigella dysenteriae. There are two known types-SLT1 and SLT2. The Shiga-like toxin is linked with hemolytic-uremic syndrome. Shiga-like toxin requires highly specific receptors on the cells' surface in order to attach and enter the cell. Species such as cattle, swine, and deer which do not carry these receptors may harbor toxigenic bacteria without any ill effect, dropping them in their feces, from where they may be distributed to humans. Shiga Like Toxin-1 Subunit B has nontoxic action, it is the functional region which binds to the receptor. The Shiga Like Toxin-1 Subunit B can be useful in vaccine study, antibody test and other functional research.
