Harris & Harris Group Notes Article on OpGen in Technology Review

NEW YORK, June 22, 2012 (GLOBE NEWSWIRE) -- Harris & Harris Group, Inc. (Nasdaq:TINY), an early-stage, active investor in transformative nanotechnology companies, notes an article published today in Technology Review that discusses one of its portfolio companies, OpGen, Inc., and the potential benefits of OpGen's optical mapping technology in identification of food-borne illnesses and the study of human diseases, including cancer.

The article highlights OpGen's optical mapping technology that can reveal repeated sequences and other structural variations in a genome that high-throughput sequencing technologies can miss. In analyzing the sequence data generated by those technologies, pieces of identical sequence can be mistakenly assumed to come from the same spot in the chromosome, so the final genome sequence does not reflect as many copies as the chromosome really contains. Because optical mapping measures the true length of chromosomes, genome scientists can determine the true structure and map of the genome of interest. The article can be viewed at http://www.technologyreview.com/news/428283/a-map-of-the-whole-genome-tracks-outbreaks/.
