Description
Hotstart HiTaq& Script III combines high-speed thermal cycling with exceptional quantification accuracy. Featuring a thermostable reverse transcriptase (HS Script III RTase) and chemical-modified hot-start Taq DNA polymerase (Hotstart HiTaq), it enables contamination-resistant, single-tube Real-Time One-Step RT-PCR with superior sensitivity—ideal for detecting low-abundance RNA targets (e.g., RNA viruses). This master mix is specifically designed for convenient, high-sensitivity one-step RT-PCR. Its unique enzyme system and specially formulated buffer ensure efficient and accurate reverse transcription and PCR amplification without requiring optimization. It delivers excellent standard curves across a broad quantitative range, enabling precise target gene quantification with high reproducibility and reliability. Suitable for hot-start RNA amplification.Product Component ListU1492576Component100T200TStorageU1492576A4×RT PCR Buffer625 µL2.5 mL-20℃U1492576BHotstart HiTaq& Script III100 µL400 µL-20℃.Protocol1.
