November 7, 2007 – Semrock, Inc., of Rochester,
NY, and Invitrogen Corp., of Carlsbad, CA, today jointly
announced the introduction of two new products that work
optimally together: the Molecular Probes® Qdot® 625
nanocrystal fluorescent label, and a
perfectly matched BrightLine fluorescence filter set
from Semrock. This
new label-filter combination allows the ultimate in brilliant
imaging or quantitation by combining Invitrogen’s
stable and technically advanced Qdot® nanocrystal
fluorescence labeling technology with Semrock’s
matched “no burn out” high performance fluorescence
filters.
Qdot® fluorescence labeling products exhibit revolutionary
imaging performance that comes from their robust nanocrystal
structure combined with a customizable surface for a
wide range of biological applications. “The new
Qdot® 625 streptavidin conjugate not only fills an
important spectral gap for dense multi-color imaging
experiments, but it also exhibits incredible brightness – even
more than our longer-wavelength Qdot® nanocrystals,” said
Dr. Stephen Chamberlain, Senior Product Manager at Invitrogen. “Coupled
with Semrock’s new high-brightness matched fluorescence
filter set, these products make an unbeatable combination
for demanding experiments such as live-cell, single-molecule
dynamic imaging.”
All Qdot® labels are not only bright, but also inherently
photostable, making them ideal for applications that
require high sensitivity and long-term photostability. “Semrock’s ‘no
burn-out’ Ion Beam Sputtering optical filter technology
is a natural fit for the photostable Qdot® labeling
technology. And we are proud to have been selected by
Invitrogen – the leader in fluorescent labeling
technology – to provide a complete solution for
this important new wavelength,” said Semrock’s
CTO, Dr. Turan Erdogan.
The new optical filters in this set have high transmission
and steep edges coupled with a carefully optimized and
narrow emission passband to match the new 625 nm Qdot® nanocrystal,
while achieving minimal crosstalk from all neighboring
Qdot® nanocrystals. Typical of Semrock’s BrightLine
fluorescence filter sets, this new filter is available
immediately from stock. Every Semrock filter, without
exception, is made with hard dielectric optical coatings
for permanent, “no burn-out” performance.
