Thermo Fisher Scientific, Waltham, Mass, has launched the Applied Biosystems TaqPath ProAmp polymerase chain reaction (PCR) master mix. The versatile master mix was developed for high-throughput genotyping and copy number variation protocols requiring accurate results from samples containing PCR inhibitors. Designed to deliver sensitive and reproducible results from genomic DNA targets, the master mix is available in two formulations: TaqPath ProAmp multiplex master mix with mustang purple for multiplexing up to four targets, and TaqPath ProAmp master mix, which includes ROXTM as the passive reference dye. Both mixes enable measurement of ABYTM, FAMTM, and VICTM dyes, or other dyes with similar emission wavelengths. The multiplex version also permits the use of JUNTM dye, or other dyes with similar emission wavelengths, in the channel typically used to measure ROX dye for single nucleotide polymorphism genotyping and other higher multiplex applications.
