Cheaper Cancer Gene Tests, by the Drop

a standard practice, says Roopom Banerjee, RainDance’s CEO and a former clinical scientist at the Dana Farber Cancer institute in Boston. The challenge has been that the fixative breaks down DNA, so most DNA-sequencing methods can’t be used on these samples. RainDance’s technology, however, can make use of even a single intact copy of a gene, so now the more than 100 million preserved cancer samples currently stored in biobanks around the world could be used in cancer research, says Banerjee.

For now, RainDance does not sell the test to doctors for use on patients, but Banerjee says it’s possible that the company’s research customers could use it to develop in-house tests.
