pDsRed2-Nuc encodes Discosoma sp. red fluorescent protein (DsRed2) fused with three copies of the nuclear localization signal (NLS) of the SV40 T-antigen. The NLS sequences are fused to the 3′-end of DsRed2. DsRed2 is a human codon-optimized variant of wild-type DsRed that has been engineered for faster maturation and lower non-specific aggregation. pDsRed2-Nuc is designed for fluorescent labeling of the nucleus in living cells.
