Harris & Harris Group Notes Metabolon and Bostwick Laboratories Marketing Agreement for Prostarix(TM)

NEW YORK, Oct. 31, 2013 (GLOBE NEWSWIRE) -- Harris & Harris Group, Inc. (Nasdaq:TINY), an investor in transformative companies enabled by disruptive science, notes the announcement by Metabolon, Inc., a leader in metabolomics-based laboratory developed tests and research services, and Bostwick Laboratories, a full-service laboratory specializing in uropathology, particularly the diagnosis of urological cancers including prostate cancer, of the signing of an exclusive multi-year marketing agreement.

Under the agreement, Bostwick will market Prostarix, a non-invasive urine test for stratifying prostate cancer risk. The test will be offered for initial cancer evaluation to determine which men are candidates for prostate biopsy and also for repeat biopsy decision-making for men with prior negative biopsies. Sample testing for Prostarix will be performed in Metabolon's CLIA-certified, CAP-accredited laboratory utilizing its state-of-the-art mass spectroscopy-based analysis technology. The Agreement provides Metabolon with access to one of the largest urology networks in the United States.

"Metabolon continues to validate its metabolomics platform with the commercial launch of Prostarix and this marketing agreement with Bostwick," said Douglas Jamison, CEO of Harris & Harris Group. "You hear a great deal about genomic-based diagnostic tests, but these metabolomic-based tests are just as powerful, meet unmet needs, and are less expensive to perform, which leads to healthcare cost savings. We are excited to be a key investor in Metabolon, a leader in these metabolomic-based laboratory developed tests. Metabolon is one of the companies in our portfolio that best represents our thinking around our BIOLOGY+ investment thesis. The combination of biology with data is extremely powerful in predicting the development of disease."
