cDNA 5X
Mastermix for easy cDNA Synthesis.
Phi(ɸ)Script™ 1st strand cDNA Mastermix is extremely user friendly while making cDNA. The mastermix (5X) is uniquely blended with RNase Inhibitors, dNTPs, Mg+2, Reaction buffers, oligo(dT) , random primers and Stabilisers. Our flagship enzyme PhiScript reverse transcriptase is provided in a separate vial. t’s an engineered form of Moloney Murine Lukemia Virus reverse transcriptase (M-MuLV-RT). Point mutations are introduced in ɸScript reverse transcriptase so as to reduce RNAse H Activity and to improve its thermal stability.

Source
PhiScript™ reverse transcriptase was cloned from MML Virus gene and expressed in E.Coli.
STUDY 1: Efficiency
Total human RNA was isolated from skeletal cells. Exon junction primers were designed for human integrin mRNA transcript.
cDNA Synthesis conditions
Total RNA template (1µL=10ng), cDNA 5X mastermix(4µL each), ɸScript Reverse Transcriptase, 1µL) and make upto 20µL using Nuclease Free Water.
Cycling conditions
25℃ (5min)
42℃ (20min)– Reverse Transcription
85℃ (10min) — Inactivates RT
-20℃ — Storage
PCR Conditions
cDNA from the condition was tested and mastermix ability was checked for 3 different sizes of the same human integrin transcript ( 150bp, 650bp and 1.6kb). Appropriate forwad and reverse primers were used.
General PCR conditions:
cDNA: 2µL, For/Rev primers: 1µL each, DX/DT Extremo mastermix: 25µL and make up 50µL using nuclease free water.
PCR Cycles:
95℃ – 2min, [95℃-30s, 60℃-30s, 72℃-1min/kb]30cycles, Final extension, 72℃ for 2min.
5µL of the sample was loaded on 1.5% agarose gel and run for 30 minutes.
STUDY 2: Reverse Transcription at various temperature
Reverse transcription temperature is crucial for certain application where RNA molecule is complex and contains high amounts secondary structure. cDNA synthesis with these samples are always challenging. But worry not. Phiscript (ɸ) reverse transcriptase has exceptional stability to work at higher temperatures. This is also one of the critical parameters during one step reverse transcription where non-specific amplification has to be reduced.
