In August, the editors of The Scientist, in collaboration with Frost & Sullivan, an international market intelligence and consulting firm, conducted a brief survey of our readers about their use of quantitative real-time PCR (qPCR) and digital PCR (dPCR) technologies. We asked readers about their usage and preferences regarding qPCR and dPCR technologies and what they wished their suppliers would improve. We analyzed data from 363 qualified respondents. The results indicate that although qPCR is considerably more popular as an entrenched laboratory technology, demand for emerging dPCR technology is growing. Explore the factors that researchers think are most important when selecting new qPCR instruments and review the top qPCR product suppliers in the charts below. (Read "Creative Emulsification" in this issue, for a discussion of innovative uses of digital emulsion PCR.)

All figures are rounded



Readers rated overall performance and data reproducibility as the most important factors in choosing real-time PCR instruments, followed closely by the ease of use, price of consumables, and customer service. Neither the brand of instrument nor remote monitoring or control was considered highly important.


Of all qPCR instrument and consumables suppliers, Life Technologies is the leading supplier by usage globally. Although respondents had fewer Qiagen instruments installed than Bio-Rad and Roche, the company appears to be gaining traction with its qPCR consumables portfolio. Integrated DNA Technologies, Sigma-Aldrich, and Promega do not provide qPCR instruments, but supply more than 15 percent of respondents with their qPCR consumables. With few exceptions, qPCR suppliers are ranked highly by researchers.
