Morgan Cook, Public Health Branch microbiologist II, provides a demonstration showing the mixing of different components of the polymerase chain reaction (PCR) using centrifuge equipment. The PCR reaction mixture is prepared using appropriate primers, probes, enzymes and buffers.
The prepared DNA extract is added to the PCR reaction mixture and is loaded onto a PCR plate.
The PCR reaction plate is placed in the ABI 7500 FAST Dx Thermocycler prior to initiating the PCR run for amplification and detection of Vibrio parahaemolyticus DNA in local oysters.
