anti-stx2B antibody product blogThe Shigatoxin 2 stx2b (Catalog #MBS584133) is an Antibody produced from Mouse and is intended for research purposes only. The product is available for immediate purchase. MyBioSource\'s Shigatoxin 2 can be used in a range of immunoassay formats including, but not limited to, FS, Immunoassay (IA), Western Blot (WB).
Application Use: For Western blotting dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:10. For inhibition of biological activity in vitro dilutions have to be made according to the amounts of toxin to be inactivated. Researchers should empirically determine the suitability of the Shigatoxin 2 stx2b for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process.
The Shigatoxin 2 stx2b product has the following accession number(s) (GI #23343475) (NCBI Accession #CAC95106.1) (Uniprot Accession #Q8HA13). Researchers may be interested in using Bioinformatics databases such as those available at The National Center for Biotechnology Information (NCBI) website for more information about accession numbers and the proteins they represent. Even researchers unfamiliar with bioinformatics databases will find the NCBI databases to be quite user friendly and useful.

Product Description: The monoclonal antibody 11E10 recognizes the 2A subunit of Shiga-like toxin 2. Shiga-like toxins (SLTs), are also called Verotoxins. 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. Antibodies to SLT-II can also neutralize a variant of SLT-II (designated SLT-Iiv) produced by strains of E.coli that cause edema. SLT-IIv is cytotoxic for Vero but not HeLa cells, distinguishing it from SLT-II. 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.
In general, we may offer more than one antibody to a given target to enable options for the researcher. Available antibodies recognizing Shigatoxin 2 are readily searchable from our website. Different antibodies against the same target such as Shigatoxin 2 may be optimized or tested for different applications and species. This enables researchers to select the option that may be best for their model system, to screen more than antibody to determine which one may be best for their model system, as well as to use more than one antibody to follow up on and validate their results.
