NORTHBROOK, Ill., May 19, 2011 (GLOBE NEWSWIRE) -- Nanosphere, Inc. (Nasdaq:NSPH), a leader in the development and commercialization of advanced molecular diagnostics systems, announced today that it will release early stage research data on potential cancer biomarkers requiring high sensitivity in an abstract for the annual meeting of the American Society of Clinical Oncology (ASCO) to be held in Chicago from June 3 to 7, 2011.

The early data suggests that three of Nanosphere's ultra-sensitive protein assays demonstrate potential clinical relevance in bladder, kidney and prostate cancers. The assays were developed and run using the Verisens™ high-throughput research platform.

The abstract can be accessed at http://abstract.asco.org/AbstView_102_84952.html

This research data complements data presented in April at the American Association for Clinical Chemistry's (AACC) Oak Ridge Conference, and in October 2010 at the ASCO-NCI-EORTC Annual Meeting on Molecular Markers in Cancer.

About Verisens™ and Verisens™ HT protein biomarker assays (RUO)

Verisens™ and Verisens™ HT comprise an in-vitro diagnostic assay for the high-sensitivity detection and quantification of protein and autoantibody biomarkers. Nanosphere is engaged in cancer research and validation for protein biomarkers that require high sensitivity, independently and with commercial collaborations.

In addition to cancer biomarkers, Nanosphere also provides a research-use-only cardiotoxicity assay for assessment of cancer therapeutics. The assay is based on an extremely sensitive human troponin assay. There is also a similar assay for rat troponin useful in pre-clinical studies.

For additional information regarding ultra-sensitive protein biomarkers and commercial collaborations, please contact Nanosphere at biomarkers@nanosphere.us.
