DsRed2 fluorescent protein
DsRed2 retains the benefits typical of red fluorescent proteins, such as a high signal-to-noise ratio and distinct spectral properties for use in multicolor labeling experiments. DsRed2 is a variant of Discosoma sp. red fluorescent protein (drFP583) (Matz et al. 1999) with faster maturation and lower non-specific aggregation.
DsRed2 retains the benefits typical of red fluorescent proteins, such as a high signal-to-noise ratio and distinct spectral properties for use in multicolor labeling experiments. DsRed2 is a variant of Discosoma sp. red fluorescent protein (drFP583) (Matz et al. 1999) with faster maturation and lower non-specific aggregation. The DsRed2 sequence contains a series of silent base pair changes corresponding to human codon usage preferences for high expression in mammalian cells (Haas, Park, and Seed 1996). You may also be interested in DsRed-Express2, an alternative DsRed version with mutations that enhance its solubility, reduce its green emission, and accelerate its maturation.
Overview
- DsRed2 excitation and emission maxima are 563 and 582 nm, respectively
- High solubility and low aggregation
- DsRed-Express2 is an alternative DsRed version with mutations that enhance its solubility, reduce its green emission, and accelerate its maturation
