KPL to sell fluorescent conjugates developed using DyLight Technology

ROCKFORD, Ill. (Sept. 3, 2008) – Thermo Fisher Scientific Inc., the world leader in serving science, and KPL, Inc. announced today the signing of a non-exclusive agreement giving KPL global rights to use Thermo Scientific DyLight™ Fluorescent Dyes in combination with KPL’s extensive line of antibodies and proteins.

KPL conjugates DyLight dyes to its range of affinity-purified antibodies to meet a variety of needs for sensitive fluorescent detection. The performance of KPL’s antibodies, combined with the brightness of DyLight dyes, offers the life science research market a means for achieving brilliant, multicolor analysis in fluorescence microscopy, Western blotting, flow cytometry and related fluorescent applications. KPL is expanding its offering of DyLight conjugates later this year using a complete series of DyLight dyes across the visible spectrum. Current products are available through the KPL sales catalog.

DyLight fluorescent dyes offer a superior choice over other commercially available fluorescent dyes. They are water-soluble and provide high-fluorescence intensity in many applications, while maintaining excellent photostability across a broad range of pH values. DyLight dyes are available over a wide range of spectra and match the output wavelengths of common fluorescence instrumentation.

“Researchers will benefit from the combination of brilliant DyLight dyes and KPL’s highperformance antibodies and streptavidin,” says Les Kirkegaard, director of marketing for KPL. “We are pleased to be working with Thermo Fisher Scientific to offer a wide range of fluorescent conjugates to our researcher customers and manufacturing partners.”

“Our goal is to equip researchers with increasingly better tools, such as the DyLight Series of Fluorescent Dyes that increase their efficiency and advance their discoveries,” says Gary Shiels, Ph.D., director of marketing for Thermo Scientific Pierce Protein Research.
