SuperScript™ VILO™ Master Mix (Invitrogen™)

SuperScript VILO Master Mix is a first-strand cDNA synthesis master mix for two-step RT-qPCR applications. The master mix combines SuperScript III Reverse Transcriptase (RT) and other RT reaction components in a single-tube format to enable reliable first-strand synthesis and high cDNA yields from a wide range of input RNA concentrations. The high RT efficiency of SuperScript III RT and the optimized formulation allow the master mix to deliver high linearity in cDNA synthesis across a broad range of input RNA template for two-step quantitative RT-PCR (qRT-PCR) assays.

Note: For superior cDNA synthesis performance in RT-qPCR applications, we recommend SuperScript IV VILO Master Mix or SuperScript IV VILO Master Mix with ezDNase Enzyme. SuperScript IV VILO Master Mix elevates the trusted VILO technology to the next level with the highly processive and thermostable SuperScript IV RT and further optimized buffer. The master mix enables efficient cDNA synthesis at higher temperatures in less time and provides superior cDNA yield and sensitivity even with suboptimal purity or scarce templates.

SuperScript™ III Reverse Transcriptase (Invitrogen™)

Invitrogen SuperScript III Reverse Transcriptase is a genetically engineered MMLV reverse transcriptase (RT) that was created by introduction of several mutations for reduced RNase H activity, increased half-life, and improved thermal stability. SuperScript III RT offers higher cDNA yields, improved cDNA lengths, improved efficiency on GC-rich target RNAs, and overall better performance than wild-type MMLV and MMLV RNase H-minus enzymes.

SuperScript RTs are the most highly trusted and widely used RTs with over 50,000 citations, reviews, and publications to date.

Note: The latest member of the SuperScript RT family, SuperScript IV Reverse Transcriptase, features enhanced thermostability, processivity, yields, and performance with any RNA samples, including those of suboptimal purity or integrity.

Maxima Reverse Transcriptase (200 U/µL) (Thermo Scientific™)

Thermo Scientific Maxima Reverse Transcriptase (RT) was developed through in vitro evolution of M-MuLV RT. The enzyme possesses an RNA-dependent and DNA-dependent polymerase activity as well as RNase H activity. The engineered enzyme features dramatically improved thermostability and robustness, and increased synthesis rates compared to wild type M-MuLV RT.

Maxima Reverse Transcriptase is capable of reproducible cDNA synthesis from a wide range of input total RNA amounts (from 1 pg to 5 µg) at elevated temperatures (50 to 65°C), which makes this enzyme an ideal tool for two step RT-qPCR (see supporting data).

Due to its high thermostability, Maxima enzyme maintains full activity during the entire reverse transcription reaction, generates the highest yields of cDNA, and is able to synthesize even very long RNA transcripts up to 20 kb. The reaction temperature can be increased up to 65°C for efficient transcription of RNA regions with a high secondary structure or to improve specificity using gene specific primers. Due to its increased synthesis rate, the reverse transcriptase reaction can be completed in 15 to 30 min.
