Single molecule fluorescence spectroscopy of mutants of the Discosoma red fluorescent protein DsRed
We studied the emission of mutants of the red fluorescent protein DsRed by room temperature single molecule fluorescence spectroscopy. Bulk samples of the DsRed variant E8 show mixed green and red fluorescence of equivalent intensities individually spectrally similar to arrested green and mature red fluorescent forms of DsRed. Investigations at the single molecule level indicate that, like DsRe...
متن کاملRed fluorescent protein DsRed from Discosoma sp. as a reporter protein in higher plants.
GFP from Aequorea victoria is a standard genetic marker widely used to visualize cellular events in a noninvasive manner. For simultaneous imaging of different processes, in vivo mutants of GFP with shifted wavelength spectra (e.g., blue fluorescent protein) are conventionally used. The recently reported red fluorescent protein from Discosoma sp., DsRed, represents a new marker that can be used...
متن کاملA Rapidly Maturing Far-Red Derivative of DsRed-Express2 for Whole-Cell Labeling†
Fluorescent proteins (FPs) with far-red excitation and emission are desirable for multicolor labeling and live-animal imaging. We describe E2-Crimson, a far-red derivative of the tetrameric FP DsRed-Express2. Unlike other far-red FPs, E2-Crimson is noncytotoxic in bacterial and mammalian cells. E2-Crimson is brighter than other far-red FPs and matures substantially faster than other red and far...
متن کاملEvidence for the isomerization and decarboxylation in the photoconversion of the red fluorescent protein DsRed.
Recently, it has been shown that the red fluorescent protein DsRed undergoes photoconversion on intense irradiation, but the mechanism of the conversion has not yet been elucidated. Upon irradiation with a nanosecond-pulsed laser at 532 nm, the chromophore of DsRed absorbing at 559 nm and emitting at 583 nm (R form) converts into a super red (SR) form absorbing at 574 nm and emitting at 595 nm....
متن کاملThe nature of fluorescence emission in the red fluorescent protein DsRed, revealed by single-molecule detection.
Recent studies on the newly cloned red fluorescence protein DsRed from the Discosoma genus have shown its tremendous advantages: bright red fluorescence and high resistance against photobleaching. However, it has also become clear that the protein forms closely packed tetramers, and there is indication for incomplete protein maturation with unknown proportion of immature green species. We have ...
