Facts

Figure 1. Highest sensitivity with SuperScript IV VILO Master Mix across 14 TaqMan gene targets. RT efficiency of SuperScript IV VILO Master Mix compared with ten commercial first strand cDNA synthesis master mixes by RT-qPCR. Master mixes were used to synthesize cDNA in 20 µL RT reactions, per manufacturer instructions, using 1 ng of total HeLa RNA input. For qPCR, 1 µL of RT reactions was used in 10 µL Invitrogen™ EXPRESS qPCR SuperMix (Cat. No. 11785200) reactions with Applied Biosystems™ TaqMan™ primer and/or probes for gene targets indicated. qPCR results are shown normalized to fold change relative to SuperScript IV VILO Master Mix [=1/(2^(Ct SSIV VILO – Ct Competitor))].

Invitrogen™ SuperScript™ IV VILO™ Master Mix is a cDNA reaction master mix designed for two-step quantitative reverse transcription PCR (RT-qPCR). It elevates the trusted VILO™ technology to the next level with the use of the new highly processive and thermostable Invitrogen™ SuperScript™ IV Reverse Transcriptase (RT) enzyme, which allows cDNA reaction to occur at higher temperatures and in less time. The SuperScript IV RT gives the highest cDNA yields and sensitivity even with suboptimal purity or scarce templates. With the SuperScript IV VILO Master Mix, the RT-qPCR workflow is further accelerated with the extremely fast and simple gDNA removal approach. It dramatically reduces the reverse transcription protocol time and reduces variation related to possible RNA loss or damage during the conventional DNase step. SuperScript IV VILO Master Mix is your new tool to enable more efficient and reproducible RT-qPCR.

Sensitivity and perfect linearity in a 10-minute reactionThe high processivity of SuperScript IV RT enzyme in SuperScript IV VILO Master Mix allows completion of RT reaction in 10 minutes. In this short reaction time, the master mix is capable of generating higher cDNA yields compared to those obtained by lengthier competitor protocols (Figure 1)—keeping the perfect linearity typical for VILO™ products (Figure 2). We compared several different cDNA synthesis kits in fourteen different RT-qPCR assays using low starting-RNA input and found SuperScript IV VILO Master Mix produced highest efficiency results. Compared with other competitors, SuperScript IV VILO Master Mix consistently lowered Ct values by >2 cycles (Figure 4).

Figure 2. Perfect linearity and lower Ct value with SuperScript IV VILO Master Mix. SuperScript IV VILO Master Mix compared by RT-qPCR with seven commercial master mixes using 5 orders of magnitude (10 pg–1 µg) of total HeLa RNA input in 20 µL RT reactions. Linearity for Applied Biosystems™ TaqMan™ GAPDH target shown in graph corresponds to slope and R2 calculated from Ct values for each formulation as determined by qPCR in 10 µL reactions using EXPRESS qPCR SuperMix (SuperScript IV VILO Master Mix effi ciency = 102.1%, slope = -3.3, and R2 = 0.99).

Improved performance on challenging samplesWith high processivity and affi nity to RNA, SuperScript IV RT has been shown to result in improved cDNA synthesis performance on samples that usually are considered challenging, such as degraded RNA and/or RNA containing inhibitors.

To demonstrate the effi ciency of SuperScript IV VILO Master Mix in the presence of a variety of inhibitors, SuperScript IV VILO Master Mix was compared with other commercially available cDNA synthesis kits in RT-qPCR. Ct values generated by competing kits were normalized to Ct values of SuperScript IV VILO Master Mix using the equation: Normalized Y values = [1/(2^(Ct SSIV VILO – Ct

Competitor))]. As exhibited in Figure 3A, SuperScript IV VILO had the highest effi ciency among all cDNA synthesis kits in the presence or absence of inhibitors shown.

Similarly, when SuperScript IV VILO Master Mix is tested with RNA purifi ed from frozen tissue samples that commonly cause low reverse transcription effi ciency, improved performance over other cDNA synthesis kits or master mixes is also observed (Figure 3B).

Consistently higher cDNA yields across a variety of gene targetsTo evaluate the effi ciency of SuperScript IV VILO Master Mix on a wide variety of gene targets, we compared it to other cDNA synthesis kits for RT-qPCR applications using a panel of 96 gene targets (Figure 4). ∆Ct values for SuperScript IV VILO Master Mix and competitors are depicted in the graph. For 96% of targets evaluated, SuperScript IV VILO Master Mix achieved greater than 2 Ct values lower than competitors and SuperScript VILO Master Mix, and overall generates higher cDNA yields.

Figure 3. Higher RT efficiency on challenging samples using SuperScript IV VILO Master Mix. (A) SuperScript IV VILO Master MIx was compared to eight other master mixes.using 100 ng total HeLaRNA in 20 µL RT reactions plus or minus the concentration of the inhibitors indicated. Performance in qPCR was evaluated in 10 µL reactions with TaqMan primer and/or probes for the B2M gene targets using EXPRESS qPCR SuperMix. (B) SuperScript IV VILO Master MIx was compared with five other commercial master mixes using 50 ng of RNA derived from frozen tissue RNA in 20 µL RT reactions. Performance in qPCR was evaluated in 10 µL reactions with TaqMan primer and/or probes for the six gene targets using EXPRESS qPCR SuperMix.

Integrated gDNA removal step for accurate quantificationMany RNA isolation kits and methods do not generate RNA that is completely DNA-free; therefore gDNA elimination remains a critical step in RT-qPCR workflow as residual DNA may lead to false-positive, higher background or lower assay sensitivity. The SuperScript IV VILO Master Mix with Invitrogen™ ezDNase provides a simplified workflow that includes a 2-minute genomic DNA elimination step

and excludes a DNase thermal inactivation or removal step (Figure 5). ezDNase, a novel double-strand-specific, thermolabile DNase, is engineered to remove contaminating genomic DNA without affecting quality or quantity of target RNA or damaging single-stranded DNA such as primers and probes.

Figure 5. A timeline comparison between the use of traditional DNase I (top) and ezDNase (bottom).
