MILPITAS, CA--(Marketwire - September 9, 2009) - JDSU (
NASDAQ:
JDSU) (
TSX:
JDU) today announced
that it has shipped more than 1,000 Xcyte ultraviolet (UV) lasers to the
biotech industry. The Xcyte cell sorting lasers are optimized for use by
bio-analytical companies in molecular biology, pathology, immunology, plant
and marine biology applications.
Typical cell sorting processes utilize expensive and sometimes carcinogenic
bio-fluorescence tags designed to attach to targeted cells. A sample of
treated cells is suspended in a liquid and directed into a hydro
dynamically-focused stream of fluid which passes through a focused UV laser
beam before the cells are separated using florescence detection and
electrostatic deflection.
The Xcyte laser has revolutionized this process by using quasi-continuous
wave (CW) UV light at high peak power to maximize tag fluorescence
efficiency, allowing users to minimize the concentration of expensive,
potentially cell-damaging fluorescence tags. Additionally, the short
pico-second pulse widths are thought to reduce the risk of live cell DNA
strands from unraveling as caused by exposure to CW UV lasers.
As the high frequency 100MHz Xcyte laser pulse rate greatly exceeds
instrument detection responsivity and tag fluorescence decay times, there
is no noticeable compromise in
signal-to-noise ratio relative to signal-to-noise ratios achieved with CW
lasers. Reducing the tag concentration and minimizing DNA unraveling helps
to maintain live cells, preserve their characteristics and prevent
long-term mutation risks for effective and reproducible bio-analytical
applications.
Product highlights include:
-- Field-proven reliability
-- Air-cooled laser with no external heat sink
-- Pulsed mode for superior instrument performance
According to Victor David, product line manager of the Communications and
Commercial Optical Products business segment at JDSU, "The reliability and
efficiency of the Xcyte laser has made it the de-facto standard for
high-accuracy cell sorting applications."
