Highly Sensitive, Easy-to-Use, Fluorescent Dye for RNA Quantitation
The QuantiFluor® RNA System contains a fluorescent RNA-binding dye that enables sensitive quantitation of small amounts of RNA in solution. Detecting and quantitating small amounts of RNA is important for many biological applications, including determining yield of in vitro transcribed RNA and measuring RNA concentration before Northern blot analysis, S1 nuclease assays, RNase protection assays, cDNA library preparation, RT-PCR and differential display PCR.
The QuantiFluor® System requires less RNA (100pg) than other RNA quantitation methods (~1µg), so you save more of your sample for downstream assays.
Improved Sensitivity vs. Absorbance and Other Fluorescent RNA Quantitation Systems
The system is designed to measure 0.1–500ng/µl RNA (from 1µl sample in a 200µl assay) and offers significantly increased sensitivity over absorbance at 260nm (NanoDrop) for samples containing low concentrations of RNA. Sensitivity is equivalent to that of Quant-iT™ RiboGreen®, with wider dynamic range.

RNA Quantitation Sensitivity and Assay Linearity
The QuantiFluor® RNA System detects as little as 0.5ng/ml RNA in a 96-well microplate assay (corresponding to 1µl of a 100ng/ml starting sample). Detection limit is defined as greater than three standard deviations above background RFU.
Easy Setup on Microplate or Single-Tube Fluorometers
The QuantiFluor® RNA System includes all the necessary reagents to quickly set up and quantitate RNA, and is easy to set up on microplate or single-tube fluorometers. The System is compatible with any fluorometer capable of measuring the appropriate fluorescence excitation and emission spectra. Compatible Promega fluorometers include:
