Molecular Devices Announces the Release of the First Live Cell Kinetic Neurotransmitter Transporter Uptake Assay Kit

    SUNNYVALE, CA, April 16 /CNW/ - Molecular Devices, a division of MDS
Analytical Technologies and a leader in innovative solutions for drug
discovery and life sciences research, today announced a breakthrough with the
launch of a live cell Neurotransmitter Transporter Uptake Assay Kit. With the
introduction of this novel assay, researchers will now have a single tool to
screen for live cell kinetic uptake of the three key neurotransmitters -
dopamine, norepinephrine and serotonin - in a homogeneous, fluorescence-based,
high-throughput screening procedure that eliminates the use of radioactive
tags or labels.
    Molecular Devices' Neurotransmitter Transporter Uptake Assay Kit
significantly improves upon current procedures that use radiolabeled
neurotransmitter or transporter inhibitors, both of which require specialized
instrumentation, detect only the assay endpoints, and are encumbered by the
disposal of radioactive materials. This assay can be used in both kinetic and
endpoint modes and is a simple, mix-and-read protocol performed in 96- or
384-well formatted microplates - ideal for use in research, including
applications in high-throughput screening and lead optimization.
    "Neurotransmitter transporters have become important pharmaceutical
targets, as they play a key role in depression and neurodegenerative diseases,
such as Alzheimer's and Parkinson's diseases. The ability to monitor live cell
uptake of dopamine, norepinephrine and serotonin neurotransmitters is critical
to better understanding these diseases," said Andy Boorn, President of MDS
Analytical Technologies. "With this assay, researchers now have kinetic and
end-point capability that will reduce their reliance upon radioactive labels."
    This new assay, like all Molecular Devices' cell-based assays, utilizes a
masking dye to extinguish extracellular fluorescence. This masking dye
technology has been exclusively licensed by Molecular Devices from Bayer AG
(patent nos. US 6,420,183, US 7,063,952, US 7,138,280 and EP 0906572). The
assay kit also includes a novel proprietary fluorescent dye that mimics the
neurotransmitters dopamine, norepinephrine and serotonin.
