qScript cDNA Synthesis Kit
Description
The qScript cDNA Synthesis Kit is a sensitive and easy-to-use solution for RNA quantification using two step RT-qPCR. The novel qScript Reaction Mix provides all the necessary components for cDNA synthesis except enzyme and RNA template. qScript reverse transcriptase is a mixture of an engineered MMLV RT and a ribonuclease inhibitor protein. This economical, highly stable stabilize, 2-component reagent system has been rigorously optimized to ensure sensitive and linear RNA detection with a wide-range of input RNA and relative abundance. Reagent performance is unaffected by repetitive freeze/thaw cycling (>20X), conferring greater ease-of-use and assay performance consistency. Oligo (dT) and random primers are pre-blended in a precise ratio to provide equal representation of 5' and 3'-sequences for accurate gene expression quantification. The resulting cDNA product is directly compatible with all qPCR chemistries or conventional end-point RT-PCR of amplified fragments ≤1 kb in length.
For gene-specific priming (GSP) or two-step RT-PCR of RNA exceeding 1kb in total length, see our qScript® Flex cDNA Kit.

Performance Data
Consistent cDNA Synthesis Efficiency - cDNA serial dilution vs. total RNA serial dilution
qPCR Standard Curve (Orange): Log fold serial dilutions of qScript-synthesized cDNA from 1 µg of HeLa cell total RNA were used as template for qPCR of ACTB using PerfeCTa™ SYBR Green SuperMix. 2-Step qRT-PCR Standard Curve (Blue): qScript cDNA Synthesis Kit was used for first-strand cDNA synthesis using log-fold serial dilutions of HeLa cell total RNA from 1 μg to 1 pg. Six replicate cDNA reactions were performed for each input quantity of RNA. 1/10th of each first-strand reaction was used for qPCR of the ACTB gene using PerfeCTa™ SYBR Green SuperMix. Concordance of the two standard curves is indicative of consistent conversion of RNA into cDNA with high efficiency at each amount of RNA tested. qScript cDNA Synthesis Kit enables reliable quantification of RNAs from low amounts of starting material.
