RT-PCR Quick Master Mix provides a 2 x Master Mix for RT-PCR using a thermostable DNA polymerase derived from Thermus thermophilus (Tth) HB8 (1). Tth DNA polymerase exhibits reverse transcriptase activity in addition to DNA polymerase activity in the presence of Mn2+ ions. Therefore, this system enables "one-step RT-PCR" including reverse transcription and PCR steps. This kit is suitable for high-throughput RT-PCR, and decreases contamination risks.
- This kit enables one-step RT-PCR including reverse transcription and PCR steps. This kit is suitable for high-throughput RT-PCR and decreases contamination risks.
- Compared with normal reverse transcriptases from retroviruses (e.g., M-MLV reverse transcriptase), Tth DNA polymerase can work at a higher temperature. Therefore, this kit has the advantage of amplifying targets with complex conformations and GC-rich content.
- Hot-start technology using anti-Tth DNA polymerase antibodies enables highly efficient and specific amplification.
- One-step RT-PCR

Example 1.Comparison of kit sensitivity
The target gene (human G3PDH: 450 bp) was amplified using in vitro translated G3PDH mRNA with one-step RT-PCR kits. As shown in Fig.1, the RT-PCR Master Mix [Code No. PCR-311] exhibited greater sensitivity than the other commercial kit.

Example 2.Detection of cdc2 mRNA using one-step RT-PCR
The human cdc2 gene (900 bp) was amplified using mRNA (5 ng and 0.5 ng) purified from a human cell line. As shown in Fig. 2, target genes were successfully amplified using the RT-PCR Quick Master Mix.
