pDsRed-Express-N1 encodes DsRed-Express, a variant of Discosoma sp. red fluorescent protein (DsRed). DsRed-Express contains nine amino acid substitutions (as compared to DsRed1), which improve the solubility, increase the maturation rate, and decrease the level of residual green emission. pDsRed-Express allows genes cloned into the multiple cloning site (MCS) upstream of the DsRed-Express coding sequence to be expressed as fusions to the N-terminus of DsRed-Express. The unmodified vector will express DsRed-Express in mammalian cells.
