Fast, Simple and Accurate

Nucleic Acid Quantification

Accurate nucleic acid quantitation is an essential step in DNA and RNA sample preparation and regularly contributes to the success (or failure) of various downstream molecular experiments. Methods commonly used to quantify DNA and RNA include absorbance (UV-Vis) measurements, fluorescence measurements, and real-time polymerase chain reaction (qPCR). While each method presents its advantages, choosing the right technology can save significant time and money and depends mainly on the experimental need and the intended downstream application.

For efficient and effective nucleic acid quantitation, AAT Bioquest offers a range of products to help you get the job done , including labelling solutions for electrophoresis gels, Plate readers and tube fluorimeters.

Gelite™ Safe DNA Gel stain. Nucleic acid stains for agarose and polyacrylamide gel electrophoresis.

Figure 1. Comparison of DNA detection in 1% agarose gel in TBE buffer using Gelite™ Safe, EtBr, and SYBR® Safe. Two-fold serial dilutions of 1 kb DNA ladder were loaded in amounts of 100 ng, 50 ng, and 25 ng from left to right. Gels were stained for 60 minutes with Gelite™ Safe, EtBr, and SYBR® Safe according to the manufacturer's recommended concentrations and imaged using the ChemiDoc™ Imaging System (Bio-Rad®). Gels were illuminated using a 300 nm transilluminator fitted with a GelGreen filter.

Figure 2. Comparison of DNA detection in 1% agarose gel in TBE buffer using Gelite™ Safe, SYBR® Safe, and EtBr. Two-fold serial dilutions of 1 kb DNA ladder were loaded in amounts of 86 ng, 43 ng, 21.5 ng, 10.7 ng, 5.3 ng, 2.6 ng, 1.3 ng, and 0.5 ng from left to right. Gels were imaged using a 300 nm transilluminator in ChemiDoc™ Imaging System (Bio-Rad®).

Gelite™ Safe DNA Gel Stain. Gelite™ Safe exhibits a considerable fluorescence enhancement by several orders of magnitude greater than that of EtBr. Gelite™ Safe was optimized to be compatible with various instruments, including UV and blue-light transiluminators, gel documentation systems, and laser scanners. It is the first single formulation that can be used in either the green or red channel at your preference. Unlike the membrane-permeant SYBR® Green, which is highly toxic to cells and the environment, the membrane-impermeant properties of Gelite™ Safe make it a much safer and noncytotoxic alternative.
