Simultaneous, qualitative detection and differentiation of noroviruses from genogroups I, II and IV is possible with this kit using a one-step real-time reverse transcriptase PCR. Based on primers and probes of the ISO/TS 15216 method and §64 German Food and Feed Code (LFGB), the foodproof® Norovirus Detection Kit (GI, GII, GIV) contains an additional phage process control. This kit is intended for food testing purposes, and thus was verified for performance with a large variety of foods. This verification was made in conjunction with the foodproof® Virus Sample Preparation Kit to extract highly purified norovirus RNA from food. Applicability of the foodproof® Norovirus Detection Kit (GI, GII, GIV) has been shown on all open real-time PCR platforms with appropriate technology for monitoring labeled, 5' nuclease probes.
