E. coli O157 Rapid Food Testing
E. coli O157-AD “SEIKEN” is an O157 LPS antigen detection kit implementing magnetic beads coated with a monoclonal antibody to concentrate the antigen for sensitive detection. Two enrichment protocols, 6 and 18 hours, are available (sensitivity: 1 CFU/g and 0.04 CFU/g, respectively). Each uses proprietary media for optimal growth of E. coli O157 (magnetic rack sold separately).
E. coli O157 Latex Test
LPS antigen extraction procedure based on a colony sweep method from selective media for more sensitive and cost-effective screening, giving results in as little as 10 minutes. The risk of laboratory infection is decreased while increasing specificity for colony sweeping and direct stool screen when acute infection is suspected.
EHEC IMS (O157, O111, O26)
This immunomagnetic separation (IMS) kit has useful applications in clinical, veterinary and environmental settings in addition to food isolation/detection. Isolation efficiency is increased significantly (up to 100 times) because the test uses a highly specific monoclonal antibody against O157 LPS molecule. IMS products for E. coli O26 and E. coli O111 are also available.
Escherichia coli Antisera
The widest E. coli antisera range available commercially, comprised of two sets. Set 1 contains 8 polyvalent and 43 monovalent O antisera (2 mil x 51), Set 2 includes 22 H antisera (5ml x 22).E. coli cells are taken from a culture plate and mixed with antisera on a glass slide. Antisera against toxigenic E. coli pili are also available (K88, K99, 987P).
