About this kit

E. coli O157:H7 is a pathogenic strain of Escherichia coli bacteria. Often a food-borne pathogen, it can cause digestive illness. PMA-based viability PCR to detect E. coli O157:H7 has been reported using the primers provided in the kit, and ORF Z3276 was shown to be specific for strain O157:H7 . These primers have been validated at Biotium for real-time qPCR using Forget-Me-Not™ EvaGreen® qPCR Master Mix. For pan-E. coli primers to detect other strains of E. coli besides O157:H7, please see kit 31050.
