MegaFi™ One-Step RT-PCR is an enzyme mix of OneScript® Hot Reverse Transcriptase and MegaFi™ Fidelity DNA Polymerase with RNaseOFF Ribonuclease Inhibitor, gel loading dye, and all other necessary reagents in a single One-Step 2X RT-PCR Buffer for both highly sensitive and specific reverse transcription and high fidelity PCR amplification in a single reaction tube from any RNA template. The kit provides flexibility in choosing desired primers for use with a proprietary RT-PCR buffer containing stabilizers and enhancers that optimize the two reactions in a “single step”. This kit offers simple, efficient reaction setup, and is a reliable alternative to conventional “two-step” sequential RT-PCR.
