Iq-check STEC virx PCR detection kit
iQ-Check STEC VirX detects STEC virulence genes and Big-6 serogroups plus E. coli O157:H7 in raw beef, raw milk products, produce, and environmental samples with next-day results.
Overview
Shiga toxin-producing E. coli (STEC) is an evolving regulatory target — USDA FSIS has progressively expanded the list of STEC serogroups classified as adulterants in raw beef. The iQ-Check STEC VirX kit detects the key virulence genes (stx and eae) along with the Big-6 non-O157 serogroups (O26, O45, O103, O111, O121, O145) and E. coli O157:H7 in a comprehensive screening workflow. Next-day results from raw beef meats, raw milk products, produce, and environmental samples.
