Arcturus of Mountain View, Calif., has rolled out a new version of its RiboAmp RNA Amplification Kit, which it says takes only six hours per round. The kit includes low-elution volume DNA and RNA purification columns and reagents, which are designed for obtaining large amounts of aRNA from minute sample sizes. “It used to take two full days to get two rounds, now it takes one day,” an Arcturus representative said. The kit costs $695, but the company is offering an introductory buy-one-get-one-free special.
