The new red fluorescent protein, DsRed, from Clontech can be viewed, and imaged, with a variety of filter sets due to its broad absorption and emission spectra. Using HeLa cells transfected with the DsRed protein, kindly provided by Clontech, we obtained excellent images with either the HQ TRITC/Cy3™ ( 41002c or 41002b) cubes or the HQ Texas
Red™ set (41004). We also found that a custom set we have made for several researchers worked very well, as did the Phycoerythrin set (41003).
