Microarrays are a vital tool in research on microRNAs, the tiny noncoding stretches of genetic material that regulate messenger RNA. They can't be beat for reading the microRNA "fingerprints" unique to disease states. But keeping up with this super hot field is a challenge for commercial microarray makers, and competition is fierce.
