Questions about which mix is best for your application?
Chat with a SpecialistThe Advantages of Thermal Stability
Chai master mixes are designed to be stable at 25 ºC for at least four weeks, with some lasting three months. High-stability mixes offer two key benefits:
More reliable, easier to use
Master mix degradation is a leading cause of inconsistent Cq values in PCR. Most commercial master mixes are stable in the freezer but start to degrade the moment they’re taken out.
When large plate-based experiments can take over an hour just to set up, it can be hard to control for the effects of enzyme degradation.
With our unique temperature stability and aptamer-based hot start, reactions can be set up without ice or other headaches. This also helps reduce waste in cases when mixes are left out during lunch or even overnight. Chai mixes can undergo 20 freeze/thaw cycles with no degradation, eliminating the need for extensive aliquoting. If you do store your mixes at 4 ºC, they’ll be stable for six months.
Cost-Effective Shipping and Flexible Logistics
Chai master mixes’ high stability also helps make shipping more economical and reliable. It avoids the cost and weight of ice packs, while preserving performance during shipping delays. Our Sahara master mixes, which are stable for three months at 25 ºC–and eight straight days at 50 ºC–can be a huge help for researchers in remote locations without reliable cold chain, shipping, or refrigeration.
Chai’s Sahara Universal qPCR Master Mix gives consistent Cq values even after eight days at 50 ºC
Real innovations for real-world testing
Inhibition Tolerance
Chai’s master mixes provide extraction-free PCR from “dirty” samples like blood, saliva, food & beverage, and environmental water.
By using biochemistry to overcome common inhibitors, Chai master mixes eliminate the need for costly, time-consuming purification steps like spin columns.
Inhibition-tolerance also provides better research results, preventing residual inhibitors that cause variability even with cleaner samples.
Get Better Melt and HRM Curves with Chai Green Dye
Chai Green binds to DNA’s minor groove, making it vastly less inhibitory than dyes such as SYBR Green I. This allows use at much higher concentrations, giving you brilliant melt curves and HRM curves that can be used to identify individual SNPs.

Prevent False Positives with UNG Carry-over Protection
PCR is remarkably sensitive, making it incredibly easy for the amplicons produced by one PCR reaction to contaminate the next. This can cause false positives or amplification of NTC controls.
To avoid this, labs traditionally use a unidirectional workflow: setting up PCR reactions in one area, running PCR in another, and ideally placing PCR instruments under negative pressure. However these extra steps are impractical for many labs.
Chai’s UNG Carry-over Protection system provides an easier, more reliable alternative. By substituting dTTP with dUTP, amplicons can be differentiated from actual targets. If contaminated amplicons do make their way into a future PCR reaction, they will be digested by an Uracil N-glycosylase (UNG) enzyme, preventing it from being amplified and producing a false signal.
