E. coli OK O antisera for live culture
OK O antisera are suitable for screening for surface antigens on live cultures, and are particularly suited to test for known EPEC and/or STEC (Shiga toxin-producing E.coli, also known as VTEC: Verocytotoxin-producing E.coli) serotypes.
A positive agglutination test is not indicative of the presence of relevant virulence genes. Positive isolates should therefore be investigated further for virulence factors.
Product description
OK O antisera are polyclonal antisera from rabbits. Serum contains antibodies against several surface antigens . For this reason OK O antisera are intended only for screening and must always be confirmed with O serotyping. OK O antisera are supplied in dropper bottles of 3 mL ready-to-use antiserum, sufficient for at least 150 reactions.
How to use
Place a small drop (approximately 20 μL) of antisera on a glass slide. Transfer culture from two to three colonies to the drop of antiserum and mix well. A positive result will be visible to the unaided eye as agglutination within 10 seconds. Positive slide results need to be confirmed with O antisera for boiled culture.
