The Path-ID™ Multiplex One-Step RT-PCR Kit is designed for multiplex, quantitative, reverse transcription PCR (qRT-PCR). It is optimized for the amplification of up to four targets simultaneously using your RNA samples and TaqMan® primer⁄probe sets. Reactions are run using a single-tube, one-step procedure to reverse-transcribe the RNA and amplify your targets. The kit contains a Multiplex Enzyme Mix with Arrayscript™ reverse transcriptase and AmpliTaq Gold® DNA Polymerase, and a buffer mix.
