Portelite™ Fluorimetric DNA Quantitation Kit with Broad Dynamic Range

Optimized for Cytocite™ and Qubit™ Fluorometers

DNA Quantitation is a very important task in DNA sample preparations for various analyses. Portelite™ Fluorimetric DNA Quantitation Kit provides a rapid method to quantify dsDNA with Helixyte™ Green BR using a hand-held fluorometer. It is optimized for Cytocite™ and Qubit™ fluorometers. Portelite™ Fluorimetric DNA Quantitation assay is linear over three orders of magnitude. The assay is highly selective for double-stranded DNA (dsDNA) over RNA and is optimized for measuring dsDNA concentrations from 10 pg/µL to 10 ng/µL. Helixyte™ Green BR exhibits large fluorescence enhancement upon binding to dsDNA, and it is a few magnitudes more sensitive than UV absorbance readings.

DNA standard curve generated using Portelite™ Fluorimetric DNA Quantitation Kit with Broad Dynamic Range. Fluorescence intensity was quantified using green fluorescence channel, regression model was calculated using linear fit.
