Prolinx Inc. Announces Distribution Agreement with VWR International for RapXtract Superparamagnetic Separation Technology

Bothell, WA, USA – Prolinx, Inc. today announced that it has signed a distribution agreement with VWR International of West Chester, Pennsylvania. VWR, a leading worldwide distributor of scientific equipment, supplies, chemicals and furniture, will distribute the Prolinx RapXtract® Superparamagnetic Separation Technology and accessories in the United States and Canada. RapXtract separation technology is used in DNA sequencing and gene expression arrays used widely in life science research and biotechnology.

RapXtract Superparamagnetic Technology is based upon proprietary superparamagnetic particles that use mass action to remove dye labeled precursors from nucleic acid labeling reactions. The technology presents a paradigm shift for purification due to its unique method. The technology "reverse purification" enables full automation, reduces sample-processing time and allows for minimum sample volumes as required by high throughput laboratories for use in applications such as whole genome analysis, single-nucleotide polymorphism discovery, drug discovery research, toxicology analysis and pharmacogenomics. Prolinx currently offers two product lines based upon the RapXtract Technology, RapXtract Dye Terminator Removal Kits and RapXtract Fluorescent Nucleic Acid Purification Kit.

"Accessing the supply chain management capabilities of a world class distribution organization like VWR International is essential for a company with leading edge technology like Prolinx," stated Jim Mahoney, president and CEO, Prolinx, Inc. "We expect this agreement to significantly impact our market penetration and revenue going forward."

"Prolinx is a truly innovative company and we at VWR look forward to this relationship," stated Ed Sapp, Director of Marketing for Life Sciences at VWR International.
