Semrock and Invitrogen Introduce Unique New Products

Quantum Dots and Brightline filtersSemrock, 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.
