Sahara One-Step RT-qPCR Master Mix
- Multiplex up to four RT-qPCR reactions with no loss of efficiency
- Thermally stable mix withstands 40 ºC for seven days without loss of performance
- Fast 5 minute reverse transcription step
- Overcomes inhibition in crude extracts and environmental samples
- License-free for commercial or diagnostic use
Sahara One-Step RT-qPCR Master Mix is a high performance mix for multiplex, probe-based quantitative reverse transcription PCR (RT-qPCR). It amplifies RNA targets at high efficiency while resisting PCR inhibitors. The one-step mix allows cDNA synthesis and subsequent PCR amplification to be performed in a single reaction, maximizing operational efficiency and sensitivity.
Extreme Thermal Stability
Stable at 40 ºC for seven days, or 25 ºC for weeks, Sahara One-Step
Fast PCR and Reverse Transcription
The fast reaction mix requires only 5 minutes for reverse transcription, and can subsequently perform 40 cycles of amplification in 20 minutes.
Amplifies Everything Without Inhibition
Sahara One-Step RT-qPCR Master Mix has been validated against mRNA, rRNA, viral RNA, and genomic DNA targets from a wide range of organisms. Numerous enhancers bind & inactivate PCR inhibitors, allowing amplification from crude extracts. The mix amplifies GC-rich targets up to 70%
Safeguard Against Carry-over Contamination
The mix contains a 90% dUTP/dTTP ratio, allowing amplicons to be selectively degraded. If you later encounter carry-over contamination resulting in false positives/amplification of NTC reactions, switching to the Sahara One-Step RT-qPCR Master Mix with UNG will degrade carry-over contamination.
