Opis ogólny

Monoclonal Anti-Shiga Toxin 1, B Subunit-FITC (mouse IgG1 isotype) is derived from the hybridoma 13C4 produced by the fusion of mouse myeloma cells and splenocytes from BALB/c mice. The Shiga toxins are a family of related protein toxins secreted by certain types of bacteria. Shiga toxin (Stx) is produced by Shigella dysenteriae; whereas, the Shiga-like toxins, Stx1 and Stx2, with a few known isoforms, are secreted by specific strains of Escherichia coli named Shiga-toxin-producing E. coli (STEC) such as E. coli O157:H7. Stx1 is identical to Stx and the Stx2 isoforms shares 60% similarity with STX. Howevere, the toxin structure is conserved. Shiga toxins consist of two polypeptides: A and B.

Specyficzność

Monoclonal Anti-Shiga Toxin 1, B Subunit -FITC recognizes the B subunit of Shiga holotoxin.

Immunogen

Purifed Shiga-like toxin from E. coli H30.

Zastosowanie

Anti-Shiga Toxin 1, B Subunit-FITC antibody, Mouse monoclonal may be used in flow cytometry.

Działania biochem./fizjol.

The STX catalytic A subunit has RNA N-glycosidase activity that inhibits eukaryotic protein synthesis. The B subunits form a pentamer, which recognizes and binds to the functional cell-surface receptor globotriaosylceramide [Gb3, Galα (1-4)-Galβ (1-4)-Glcβ1-ceramide]. Shiga toxins are implicated in bloody diarrhea and hemorrhagic colitis in humans, which may lead to fatal systemic complications. Gb3 is overexpressed in membranes of numerous tumor cells, therefore, STxB binding to Gb3 receptors may be useful in cancer cell imaging.

Postać fizyczna

Supplied as a solution in 0.01 M phosphate buffered saline pH 7.4 and 15 mM sodium azide as a preservative.

Przechowywanie i stabilność

For continuous use, store at 2–8 °C protected from light for up to one month. For extended storage, freeze in working aliquots. Repeated freezing and thawing is not recommended. If slight turbidity occurs upon prolonged storage, clarify the solution by centrifugation before use. Working dilution samples should be discarded if not used within 12 hours. Protect from prolonged exposure to light.

Inne uwagi

In order to obtain best results in different techniques and preparations we recommend determining optimal working concentration by titration test.
