Simultaneous Five-color Fluorescence Imaging with the World's First “Penta-Sedat” Optical Filter Set

PentaSedat Set ROCHESTER, N.Y. – Semrock has broken new ground again this year with the release of its new "Penta-Sedat" multiband fluorescence filter set, DA/FI/TR/Cy5/Cy7-5X5M. The eleven-filter set enables imaging of five distinct fluorophores simultaneously for the most complex imaging schemes. With the creation of the unique penta-beamsplitter, FF408/504/581/667/672-Di01, and an improved Cy7 emitter, FF02-809/81, the set allows for high-speed imaging into the near-infrared for in vivo and tissue applications, with up to four visible labels in addition. When used in higher-performance microscopes equipped with filter wheels, the quicker analysis time can bring down the overall cost of research and reduces diagnosis time.

At the heart of this new filter set is an innovative penta-beamsplitter, with guaranteed transmission, reflection, and edge steepness every bit as good as single-edge dichroic beamsplitters. "Many researchers have asked us how they can image increasingly larger numbers of fluorophores without sacrificing the fidelity of their images. Semrock's unique ability to make the most complex optical filters with our all-hard-coating ion-beam-sputtering technology makes this new five-band filter set possible," said Turan Erdogan, Chief Technology Officer.

Catalog products ordered by noon, EST will be shipped same-day.  Rapid custom-sizing is shipped in under a week and a 30-day no-hassle return policy applies to all catalog products. All Semrock filters are covered under the company's five-year warranty.
