Forget-Me-Not™ EvaGreen® qPCR Master Mixes are hot-start mixes for real-time PCR and melt curve analysis. The mixes can be used to replace any SYBR® Green master mix. A low-level blue dye helps identify wells with master mix. Available without ROX, with separate ROX, or premixed (high or low). The optional 2-color tracking system helps prevent pipetting errors and conserves time, reagents, and DNA.

EvaGreen® Dye

EvaGreen® Dye is a unique, safe DNA-binding dye ideal for qPCR and HRM analysis*. Its novel "release-on-demand" mechanism allows high dye concentration without PCR inhibition (Mao et al., 2007, BMC Biotech). Unlike other dyes, EvaGreen® Dye cannot cross cell membranes, minimizing genotoxic risk. SYBR® Green I, by contrast, is more environmentally toxic than ethidium bromide (Ohta et al., 2001, Mut. Res.).

Independent studies confirm EvaGreen® is nonmutagenic, noncytotoxic, and safe for aquatic life, making it drain-disposable. For details, download the EvaGreen® Dye Safety Report.

As an added benefit, EvaGreen®-based master mixes enable direct gel analysis without adding extra stain; the dye serves as a built-in pre-stain for easy band visualization.

Cheetah™ HotStart Taq

Cheetah™ HotStart Taq is Biotium’s proprietary chemically modified Taq polymerase designed for reducing non-specific DNA amplification in PCR. Cheetah™ Taq features a novel chemical modification that completely suppresses its activity prior to activation, and offers a much faster activation time than AmpliTaq Gold® or HotStartTaq®. Cheetah™ HotStart Taq is available in two different formulations: Cheetah™ FLEX is formulated for fast-cycling qPCR and proximity extension assays (PEA), and Cheetah™ PEA-PLEX is formulated for NGS-based high-throughput PEA.

FAQs

Forget-Me-Not™ EvaGreen® qPCR Master Mix is a hot-start EvaGreen® dye-based master mix. It uses Biotium’s proprietary chemically modified hot-start DNA Polymerase, Cheetah™ Taq. This master mix also contains a light blue tracking dye, and comes with a dark blue template dye, for two-color tracking to reduce pipetting errors. The user only needs to supply primers and template.

Forget-Me-Not™ Universal Probe Master Mix is formulated for fluorescent probe-based PCR applications. It uses Biotium’s proprietary chemically modified hot-start DNA Polymerase, Cheetah™ Taq. The user needs to supply some kind of fluorescent probe (such as TaqMan®, dual-labeled BHQ®, or Molecular Beacon) in addition to primers and template.

Biotium offers three different EvaGreen® dye-based qPCR master mixes:

  • Forget-Me-Not™ qPCR Master Mix
  • Fast EvaGreen® qPCR Master Mix
  • Fast Plus EvaGreen® qPCR Master Mix

All three master mixes contain our high-quality EvaGreen® DNA-binding dye and our fast-activating chemically-modified hotstart enzyme, Cheetah™ Taq.

Forget-Me-Not™ qPCR Master Mix is our newest master mix formulation. For most purposes this is the master mix that we would recommend, as it has many benefits: best sensitivity and signal, blue tracking dyes in the master mix and template to reduce pipetting errors, and low cost. Fast EvaGreen® qPCR Master Mix is a sensitive, general use master mix that does not contain blue tracking dyes. Fast Plus EvaGreen® qPCR Master Mix has a slightly different formulation than the regular Fast EvaGreen® qPCR Master Mix, and was designed for more challenging samples.

EvaGreen® dye is spectrally similar to FAM or SYBR® Green I, which means no change in optical settings is required for using an EvaGreen®-based master mix. However, there are several differences between the dyes.

Lower background fluorescence: EvaGreen® dye has less background than SYBR® Green I due to its novel “release-on-demand” DNA-binding mechanism.

Brighter and non-inhibitory:  EvaGreen® is less inhibitory in the PCR reaction than SYBR® Green, permitting the use of saturating dye concentration for maximal signal and better high-resolution DNA melt analysis.

Safer and more environmentally friendly: EvaGreen® dye is the first and only PCR dye to date designed to be environmentally safe.

Dye stability: EvaGreen® dye is very stable both during storage and under PCR conditions. SYBR® Green I, on the other hand, is known to degrade following multiple freeze-thaw cycles and under PCR conditions. Moreover, decomposed SYBR® Green I is reported to be even more inhibitory to PCR.

Digital PCR: EvaGreen® dye is currently the only qPCR dye to be used in droplet digital PCR (ddPCR).
