 LexaGene Holdings Inc. has revealed that its MiQLab System is the first point-of-need instrument that can be configured to perform polymerase chain reaction PCR tests using either probe-based chemistry, or SYBR Green chemistry coupled with melt curve analysis. In a statement, Dr Nathan Walsh, VP of Applications and Informatics at LexaGene, said: Traditional real-time PCR uses expensive hydrolysis probes that have long lead times for manufacturing, whereas SYBR Green-based PCR uses inexpensive primers that have much shorter lead times.
