Maximize your RT-qPCR success with optimized starting material

RT-qPCR requires both high-quality RNA as starting material and optimal conversion of the RNA to a DNA copy for accurate real-time PCR detection (qPCR). When an RNA quantitation step is added you’ll be better able to optimize your qPCR analysis.

Learn more about optimizing each step in the workflow by clicking on the tabs below.

The sensitivity and accuracy of RT-qPCR detection depends on the quality and quantity of your input cDNA, which in turn depends on the quality and integrity of the isolated RNA. One important step for avoiding false positives and background is the removal of genomic DNA.

Life Technologies Ambion® RNA purification products help simplify RNA Extraction for Real-Time PCR. You can also capture your RT-qPCR results directly from cells with Ambion® Cells-to-CT™.

The Qubit® and Quant-iT™ RNA assays provide specific, sensitive RNA and microRNA quantification, even at low concentrations, with minimal interference from contaminants.

Unlike UV absorbance readings, which are less discriminate, these assays distinguish between DNA, RNA, proteins, and free nucleotides with higher sensitivity than UV absorbance readings, making it possible to measure low-abundance samples. In addition, an intuitive format makes it easier and faster to get your quantifation results.

"NanoDrop measured DNA concentrations higher than Qubit and its consistency with dsDNA quantification by qPCR was limited to high molecular weight DNA from FF samples and cell lines, where total DNA and dsDNA quantity virtually coincide. In partially degraded DNA from FFPE samples, only Qubit proved highly reproducible and consistent with qPCR measurements.”
