qScript microRNA cDNA Synthesis Kit is intended for molecular biology applications. This product is not intended for the diagnosis, prevention or treatment of a disease.
The qScript microRNA cDNA Synthesis Kit is an optimized reagent system that reverse transcribes small single-stranded RNA into 5"-labeled cDNA using either total RNA or miRNA enriched samples.
Single-stranded RNA is first polyadenylated by poly(A) polymerase before reverse transcription into universal cDNA using high performance qScriptRT with a proprietary adapter oligo(dT) primer. The universal cDNA template enables simple and cost-effective microRNA profiling when used together with wet-lab validated PerfeCTa microRNA Assays, PerfeCTa Universal PCR Primerand PerfeCTa SYBR Green SuperMix.
We are happy to provide you the sequence of your assay so that you can continue ordering it through any vendor of your choice. To download the Excel sheet containing the assay sequences, please click HERE. Use the CTRL-F function within excel to search for your assay of interest and find the corresponding sequence.
This complete kit includes positive (human) control primer, SNORD44, that can be used to quantitate ubiquitously expressed small nucleolar RNA. In addition, the kit contains 20% extra poly(A) polymerase reaction buffer and microRNA cDNA Reaction Mix to perform (-) poly(A) polymerase and (-) reverse transciptase control reactions.
The qScript microRNA cDNA Synthesis Kit is suitable for use with total RNA or preparations pre-enriched for microRNAs. A poly(A) tail is added to microRNAs followed by cDNA synthesis using an adapter primer and qScript RT in a single-tube reaction. The resulting cDNA is ready for qPCR amplification with a Universal PCR Primer and your choice of microRNA Assays. This unique single-tube system provides ease-of-use and efficient cDNA synthesis for quantification of microRNAs with a high degree of sensitivity and specificity. PerfeCTa™ SYBR Green SuperMixes ensure compatibility with any real-time thermal cycler.
Quanta"s microRNA profiling system provides linear detection and quantification of microRNAs across total-RNA input levels spanning six orders of magnitude. This means microRNAs will be detected when present even when tissue is scarce or the microRNAs are rare.
microRNA cDNA synthesis was performed starting with log-fold dilutions of human brain total RNA (from 1.0 µg to 10 pg) using the qScript™ microRNA cDNA Synthesis Kit (Quanta) or the miScript Reverse Transcription Kit (Qiagen). 1/100th of each microRNA cDNA reaction was used in a 20 µL qPCR amplification reaction specific for hsa-let-7a using each manufacturers validated microRNA assay, qPCR mix and recommended protocol. Averaged plots for triplicate qPCR reactions for each input quantity are shown. Cycling conditions for the miScript Primer Assay with the miScript SYBR Green PCR Kit (Qiagen) consisted of 94°C, 15 min followed by 40 cycles of 94°C, 15s; 55°C, 30s and 70°C, 30s. Cycling conditions for the PerfeCTa® microRNA Assay and PerfeCTa® SYBR® Green SuperMix™ (Quanta) consisted of 95°C, 2 min followed by 40 cycles of 95°C, 5s and 60°C, 30s.
MicroRNA cDNA synthesis was performed starting with log-fold dilutions of human brain total RNA (from 1.0 µg to 100 pg) using the qScript™ MicroRNA cDNA Synthesis Kit (Quanta) or the TaqMan® microRNA Reverse Transcription Kit (ABI). 1/100th of each microRNA cDNA reaction was used in a 20 µL qPCR amplification reaction specific for hsa-miR-124 using each manufacturers validated microRNA assay, qPCR mix and recommended protocol. Averaged plots for triplicate qPCR reactions for each input quantity are shown. Cycling conditions for the TaqMan MicroRNA Assay with TaqMan Universal PCR Master Mix (ABI) consisted of 95°C, 5 min followed by 40 cycles of 95°C, 15s; 60°C, 1 min.
