EvaGreen Fluorescent DNA Stain (100µM)

Stain for intercalation DNA, Evagreen is: Non-mutagenic, non-cytotoxic and safe to aquatic life for safe handling and easy disposal down the drain


EvaGreen Fluorescent DNA Stain is well known DNA intercalator dye specially developed for DNA analysis applications including real-time PCR (qPCR) and HRM-analysis. Upon binding to DNA, the non-fluorescent dye becomes highly fluorescent while showing no detectable inhibition to the PCR process.
The high quantum yield, excellent stability and lowest inhibition toward PCR makes it the ideal fluorophore in real-time PCR applications and a superior replacement for the widely used SYBR-Green I dye.

The dye is extremely stable both thermally and hydrolytically, providing convenience during routine handling.

Vortex EvaGreen® Fluorescent DNA Stain thoroughly prior to its use. Add 1 µl EvaGreen® Fluorescent DNA Stain for each 50 µl of the assay. Please note that the preparation of a master mix is crucial in quantitative PCR reactions to reduce pipetting errors. To perform the EvaGreen-based assay simply select the optical setting for SYBR® Green on the detection instrument.

Mechanism of DNA Binding:
EvaGreen® DNA-binding dye is designed using a novel concept of DNA binding via “release-on-demand” mechanism. The dye is constructed of two monomeric DNA-binding dyes linked by a flexible spacer. In the absence of DNA, the dimeric dye assumes a looped conformation that is inactive in DNA binding. When DNA is available, the looped conformation shifts via an equilibrium to a random conformation that is capable of binding to DNA to emit fluorescence. This chemical equilibrium provides a unique mechanism to continuously supply the active form of the dye from the “reserve” (i.e., the dye in looped conformation), as more DNA is formed during a PCR process. Consequently, an EvaGreen® master mix can be formulated with relative high dye concentration to maximize fluorescence signal without PCR inhibition, making the mix suitable for both qPCR and HRM applications.
