The method, which is detailed in the current issue of Genome Biology, involves using the mean expression value of all expressed miRNAs in a given sample.

The company's lab is cleared in 48 states. The firm also said that it could earn $17 million through a license with Prometheus Laboratories.

The firm launched three microRNA-based tests during the fourth quarter, and posted a profit due to a capital gain on the sale of Auction Rate Securities to Credit Suisse. However, Rosetta only has enough cash to fund operations through mid-2010 and said that it may seek to raise additional funds.

An Affy spokesperson said the firm's interest in the market is an extension of its gene-expression profiling play, and said several "key advantages" over rival tools could enable it to profit in the market, which is poised to grow 25 percent through 2015.

An Italian research team demonstrated that miR-9 is up-regulated in two types of human immune cells during the pro-inflammatory process and may regulate a NF-kappa-B subunit.

The company is looking to differentiate itself from other players in the miRNA array market — such as Agilent Technologies, Life Technologies, Exiqon, and Febit — by stressing the "quality, performance, and affordability" of its OneArray platform.

The firm published data from a study showing that the same biomarker used in its miRNA-based test for squamous lung cancer provided 96 percent sensitivity.
