Enhanced red and far-red fluorescent proteins for in vivo imaging

Abstract

GFP and its homologs are widely used as genetically encoded labels in many in vivo imaging applications. The fluorescent proteins emitting in the longer wavelength part of the spectrum provide even more opportunities, as they ensure less autofluorescence background, higher fluorescence resonance energy transfer efficiency and much more effective light penetration for deep imaging of animal tissues. Evrogen offers a set of exceptionally bright red and far-red fluorescent proteins optimized for different applications.
