Abraxis provides anti-E. coliantibodies for the detection of human and animal pathogens. Affinity purified monoclonal and polyclonal antibodies offer excellent specificity and sensitivity for O157:H7 and non-O157 STEC (Shiga toxin-producing E. coli) testing. Abraxis has incorporated these antibodies into our highly sensitive Immunomagnetic Separation (IMS) and Latex Agglutination test (LAT) kits for O157:H7, the “Big Six” non-O157 STECs, and O104:H4. ♦ Also now available are recombinant Shiga toxins (verotoxins), as well as ELISA kits for detection of Shiga toxins.

Whether your needs are food safety, compliance, quality assurance, or research, Abraxis’ anti-bacteria antibodies, test kits, and recombinant toxins provide an extended offering of affordable test solutions for numerous formats such as ELISA, western blot, lateral flow, agglutination, immunoseparation, flow cytometry, and immunofluorescence.

Shiga Toxin ELISA Kits

The most sensitive ELISAs available, differentiating between Stx1 & Stx2, and recognizing nearly all known Shiga toxin subtypes from single colonies on agar plates (Austin Immunology (2016), 1(2): 1007). Applications available for a variety of foods, including beef, leafy greens, water, and milk.

Recombinant Shiga Toxins

These purified recombinant Shiga toxoids have a point mutation that makes them non-catalytic, and nontoxic in the Vero cell toxicity test. They can be used as standards in Shiga toxin assays, or for other research purposes. User Guide SDS
