SAN DIEGO and BILLERICA, Mass., July 29, 2013 /PRNewswire/ -- Trovagene, Inc.
(NASDAQ: TROV) and RainDance Technologies announced today that Trovagene has
adopted RainDance's RainDrop^TM Digital PCR System for research and
development, and for eventual use in the Trovagene CLIA laboratory. Trovagene
has also announced successful development of a cell-free DNA mutation assay
leveraging the RainDrop platform.

"Trovagene's DNA isolation and assay development is at the forefront of
non-invasive, cell-free cancer mutation detection and monitoring,"said Roopom
Banerjee, president and CEO of RainDance. "Utilizing our RainDrop Digital PCR
System,they have addressed a critical need by enabling the use of a
non-invasive, systemic specimen. This technology platform allows better
assessment of tumor dynamics within an individual sample."

The automated RainDrop System allows for a hundred-fold increase in the amount
of DNA that can be analyzed for cancer mutation detection, increasing
sensitivity and the ability to find rare mutations. It can analyze up to 10
million pico-liter sized droplets in a single assay, vastly improving the
probability that low-level mutations will be detected. RainDance's digital PCR
approach also enables quantification of the relative amounts of mutated DNA in
a sample.

Understanding the genomic changes that define a patient's tumor can lead to
clinically actionable information before, during and after therapy. The
ability to non-invasively detect and monitor oncogenic mutations and genomic
variations, as well as markers for resistance, may improve the overall
management of cancer and lead to improved outcomes.

"Trovagene's goal is to help improve detection and monitoring of cancer
patients undergoing treatment, particularly those with metastatic cancers,"
stated Mark Erlander, chief scientific officer of Trovagene. "Analyzing the
large amounts of DNA present in urine requires a platform capable of handling
hundreds of thousands, if not millions, of reactions. The RainDrop System is
ideally suited for this task and enables Trovagene technology to be even more

Trovagene evaluated several platforms before purchasing RainDance's RainDrop
Digital PCR System. "The high level of sensitivity and workflow improvements
made it a clear, cost-effective choice for detecting and quantifying singular
oncogene mutations from cell-free DNA," said Erlander.
