LINCOLN, Neb., June 19 — LI-COR Biosciences introduces a

new accessory, MPX(TM) (Multiplex) Blotting System, for its Quantitative

Western Blotting product line. The MPX System can be incorporated into a

variety of assays including primary and secondary antibody screening,

monoclonal antibody screening, signal transduction pathway analysis, or any

other common Western blotting procedure that generates a PVDF or

nitrocellulose blot of 7 x 8.5 cm.

Processing is as simple as clamping the blot into the MPX System,

creating up to 24 independent channels. Channel ports are low volume,

conveniently spaced, and staggered and beveled for use with multi-channel

pipettes. Other advantages include no cross contamination or cross

reactivity between channels.

LI-COR’s selection of IRDye(R) infrared dyes on the Odyssey(R) Infrared

Imaging System provides a maximum of 48 targets on a single membrane — two

per channel, and the option for quantitative analysis. Standard

chemiluminescence and colorimetric detection methods can also be used, and

can provide a maximum of 24 targets.

The Odyssey Infrared Imaging System is uniquely equipped with two

infrared channels for direct fluorescence detection with high sensitivity

and low biological background fluorescence. The superior signal to noise

ratio produced using near-infrared dyes produces results not previously

possible with visible fluorescence-based imaging systems.

LI-COR(R) Biosciences is a leading manufacturer of near-infrared

imaging platforms, analysis software, and LI-COR IRDye(R) infrared dye

reagents for genomic, proteomic, and molecular imaging applications. LI-COR

pioneered the development of near-infrared fluorescence detection systems

for DNA sequencing and today provides systems for drug discovery, protein

research, small animal imaging, and undergraduate training. LI-COR

instruments for photosynthesis, carbon dioxide analysis and light

measurement are recognized worldwide for standard-setting innovation in

plant science research and environmental monitoring. Founded in 1971, the

privately held company is based in Lincoln, Nebraska, with subsidiaries in

Germany and the United Kingdom. LI-COR systems are used in over 100

countries and are supported by a global network of distributors. More
