This product selects the IS 481 region (FAM) of Bordetella Pertussis, and designs one set of primers and fluorescent probe. The one set of primers and probe can specifically bind to the target sequences. When the PCR amplification reaction is performed, the fluorescent signal can be detected by a full-automatic fluorescent PCR detector to realize real-time online monitoring of the PCR reaction. Greatly improve the detection efficiency and shorten the detection time.
