Pyrosequencing Cuts Sample Preparation Times in Half with the New Vacuum Prep Tool


UPPSALA, Sweden, June 13, 2002 (PRIMEZONE) -- Pyrosequencing AB (Stockholm: PYRO A) today announced the worldwide launch of the Pyrosequencing(TM) Vacuum Prep Tool - the new time and labor efficient device that accurately prepares DNA samples for genetic analysis by the PSQ(TM)HS 96A System. This hand-held tool uses the speed of vacuum filtration to batch process 96 samples in a straightforward procedure that takes less than 15 minutes to perform. Speed and simplicity are further enhanced by the ergonomic bench-top workflow created by minimal pipetting and an intuitive operating procedure. The filter probes within the tool are designed for repeated use, with each set able to prepare over 50 96-well plates.

"Sample preparation for genetic analysis is often a rate-limiting step to significantly increasing throughput," said Marten Winge, Vice President Worldwide Marketing, Sales and Support. "This new companion product to the PSQ HS 96A System gives our customers what they need to prepare more samples faster and with less effort. We continue to examine innovative solutions to enhance Applied Genetic Analysis and have begun to transform several of these into products."

During 2002, Pyrosequencing expanded its product portfolio with the introduction of two new genetic analysis solutions - the PSQ HS 96A and PSQ(TM)96MA Systems. The PSQ HS 96A System is a medium to high- throughput, dedicated SNP and mutation analysis system that delivers cost efficient analysis and hours of unattended operation. The PSQ 96MA System is a multi-application solution, ideally suited for a broad range of applications within Applied Genomics. Pyrosequencing also provides high-throughput genotyping solutions with a 384-well format, currently available through an early access Preferred Technology Program (PTP(TM)).
