Clostridium perfringens are obligate anaerobic bacteria that are widely distributed in nature. Food poisoning by C. perfringens develops by eating viable bacteria of CPE (Clostridium perfringens enterotoxin) producing strain which has grown in food. This kit is for detecting CPS-producing C. perfringens, which combined NASBA (Nucleic Acid Sequence-Based Amplification) method that directly amplifies CPE mRNA and NAC (Nucleic Acid Chromatography) method that easily identified the amplicon. This kit contains NASBA primers specially designed to amplify both CPE mRNA and Internal Control (IC) in a single tube and NAC strip to identify both the amplicons on the single strip.
