pTagRFP-Golgi is a mammalian expression vector intended for red (orange) fluorescent labeling of Golgi apparatus in living cells. The vector encodes red (orange) fluorescent protein TagRFP (see reporter description) fused to Golgi targeting sequence (GTS), the fragment of human β-1,4-galactosyltransferase. GTS is fused to the TagRFP N-terminus.

TagRFP codon usage is optimized for high expression in mammalian cells (humanized) [Haas et al., 1996].
pTagRFP-Golgi vector can be used as a source of TagRFP-GTS hybrid sequence. The vector backbone contains unique restriction sites that permit its excision and further insertion into expression vector of choice.
Note: The plasmid DNA was isolated from dam+-methylated
The vector backbone contains immediate early promoter of cytomegalovirus (PCMV IE) for protein expression, SV40 origin for replication in mammalian cells expressing SV40 T-antigen, pUC origin of replication for propagation in
SV40 early promoter (PSV40) provides neomycin resistance gene (Neor) expression to select stably transfected eukaryotic cells using G418. Bacterial promoter (P) provides kanamycin resistance gene expression (Kanr) in
Expression in mammalian cells
pTagRFP-Golgi vector can be transfected into mammalian cells by any known transfection method. CMV promoter provides strong, constitutive expression of the TagRFP-GTS fusion in eukaryotic cells. If required, stable transformants can be selected using G418 [Gorman, 1985].
