E. coli O121 Immunomagnetic Separation (IMS) Beads are magnetic beads coupled with antibodies against E. coli O121 and designed for use in immunomagnetic separation procedures.
The beads are intended for the selective concentration of E. coli O121 from analytical samples, supporting subsequent isolation and confirmation on selective agars. Gold Standard Diagnostics states that the beads are used as part of the USDA-FSIS MLG Chapter 5B procedure for the detection, isolation and identification of STEC strains from meat products, carcasses and environmental sponges.
