There is an increasing need for affordable, thermostable PCR reagents that can be used for diagnostic testing in resource limited settings. The development of point-of-care devices in such settings is highly dependent on the availability and efficacy of thermostable reagents. Here, we assess the thermostability of commercial, intercalating dye-based real-time PCR master mixes. We show that several of these master mixes have thermostability and robust performance at 20 °C, 40 °C, and 45 °C for 6, 4 and 2 weeks, respectively. However, none of the master mixes that we evaluated was able to withstand more than 1 month at 45 °C incubation. Our findings have implications for clinical diagnostics in the developing world where cold-chain delivery of diagnostic assays is difficult to guarantee.
