VisEn launches new red fluorescence imaging label
VisEn Medical has launched a new red fluorescent dye for optimized labeling of biomolecules in a broad range of in vitro and in vivo research applications. 

The Bedford, Mass.-based VisEn said the new VivoTag 645 offers lower-red wavelengths, well suited for labeling and imaging of proteins, antibodies, and small molecules in a range of both in vivo and in vitro research areas.  

The fluorescence wavelength is matched for biological imaging applications on in vitro and in vivo fluorescence systems, including advanced microscopes, high content imaging and flow cytometry systems and also optimized for use with VisEn's fluorescence tomography FMT imaging systems, added the company.
