Hamamatsu Photonics Introduces the Cost-effective FDSS/uCELL Imaging Plate Reader

BRIDGEWATER, New Jersey, April 1, 2010 - Hamamatsu has announced the release of the FDSS/uCELL, an affordable new
imaging plate reader for kinetic cell-based assay development, including GPCR
and ion channel research. The uCELL ("micro cell") offers a cost-effective
way for biotechnology companies, research institutes, and clinical research
organizations to introduce the highly reliable and advanced Hamamatsu FDSS
(Functional Drug Screening System) technology to their daily operations. It
is ideally suited for labs that require access to the functionality of
expensive drug discovery instrumentation, but at lower cost.

The FDSS/uCELL is designed for fast and easy operation. It accepts plates
in either 96 or 384 well format, and is equipped with a high-sensitivity
Hamamatsu camera that images the entire plate simultaneously. This process
results in shorter readout times than conventional scanning-based systems.
Agonist/antagonist assays can be performed in the same run. Software allows
users to quickly set assay parameters in a single protocol, which can be
later transferred to an FDSS7000 for further screening. An optional washing
system enables tips to be reused several times.
