Anti-Coli O 2 is a monospecific test reagent for the serological detection and serovar determination of isolated E.coli strains from human test material or other origin.

• Method: Slide agglutination and Widal reaction. If the isolated strain has E.coli antigen, within the range of the testing reagent, antigen-antibody reaction results in a visible agglutination. A negative result is reported in the absence of agglutination.
• Range: Е.coli O 2
• Composition: A mixture of monoclonal antibodies derived from the supernatant of the culture medium of hybridoma cell lines secreting antibodies against the group specific E.coli antigen.
• Preservative: Sodium Azide (NaN3) 0.9mg/ml
• Form of the reagent: Lyophilised
• Storage: 2-8⁰C

An isolate with positive results requires testing with monospecific reagents for further characterisation and to rule out unspecific agglutinations a check by the Gruber-Widal test (confirmation test) with Gruber Widal Serum Anti-Coli O 2.

Anti-Coli O 2 is relevant to veterinary medicine in E.coli diagnostics in young poultry.
