Novel proteins with far-red fluorescence that can be easily distinguished from background autofluorescence of tissues are developed. TurboFP635 is a superbright and fast-maturing far-red fluorescent reporter for cell labeling within living tissues. TagFP635 is a bright monomeric far-red fluorescent tag for protein localization studies.

Novel monomeric red fluorescent protein TagRFP has excitation and emission maxima at 555 nm and 584 nm, respectively. TagRFP is the brightest monomeric red fluorescent protein available so far. TagRFP shows successful performance in fusions even with cellular oligomerizing proteins. Evrogen offers vectors for generation of TagRFP-tagged fusions and for expression of TagRFP and its fusions in mammalian cells as well as antibodies for immunological detection of TagRFP. Evrogen technology embodied in TagRFP is available for expanded and commercial use with an adaptable licensing program. Benefits from flexible and market-driven license options are offered for upgrade and novel development of products and applications.
