Xpress System Gets AOAC-PTM for 'Big 6' STEC

Crystal Diagnostics' Xpress System has been awarded AOAC-PTM Certifications for the six non-O157 Shiga toxin-producing E. coli  (serogroups O26, O45, O1O3, O111, O121, and O145; collectively referred to as STEC or the 'Big-6') as well as E. coli  O157, able to detect 1 cfu per 325g of raw ground beef and raw beef trim, or 200g of raw spinach.

The CDx Xpress System combines proprietary liquid crystal technology with antibody-coated paramagnetic microspheres to selectively capture and detect STEC from food matrixes, faster than other commercial systems. Want to see how it works - visit

More protocols and kits are being developed to run on the Xpress system with Listeria, Salmonella spp., and strain specific Salmonella in progress with expectations of an AOAC certified 12-hour Salmonella test by mid-2015, and Listeria shortly thereafter.
