MyTaq(TM) One-Step RT-PCR Kit has been designed for extremely sensitive and highly reproducible first-stand cDNA synthesis and subsequent PCR in a single tube (fig. 1). The kit contains the latest advances in buffer chemistry, including Bioline's ultra-pure dNTPs, together with reverse transcriptase (RT) and our new generation of very high performance, antibody-mediated hot-start DNA polymerase (MyTaq HS). This ensures that MyTaq One-Step RT-PCR Kit produces fast, highly-specific and ultrasensitive products for downstream applications. MyTaq One-Step Kit consists of reverse transcriptase, 2x MyTaq HS Mix and a potent RNase Inhibitor, RiboSafe, that are added together to create a simple to use all-in-one mix. The kit is ideal for determining the presence or absence of RNA templates and quantifying expression through qualitative, semi-quantitative or quantitative analysis of RNA transcription levels, and the one-step format is also perfect for the synthesis of double-stranded cDNA products for subsequent gene-expression analysis. The cDNA can be synthesised with starting amounts of RNA template from 3pg to 1µg, over a broad temperature range (up to 50°C (fig. 2) to overcome secondary structure and GC-rich sequences), prior to heating to 95°C to inactivate reverse transcriptase and simultaneously to activate the MyTaq(TM) HS.
