BD Pharmingen™ Green FP Vector - Nucleus is a mammalian expression vector that encodes a fusion of the green fluorescent protein (FP)
from Aequorea coerulescens with three copies of the nuclear localization signal (NLS) of the simian virus 40 (SV40) large T antigen. The
NLS sequences are fused to the 3’-end of green FP. In order to increase the translation efficiency in mammalian cells, a Kozak consensus
translation initiation site has been introduced to the 5’-end of the green FP open reading frame, and its sequence has been optimized with
human codons. The green FP fusion is expressed under the control of the immediate early promoter of cytomegalovirus (P CMV ie), and its
sequence is followed by downstream SV40 polyadenylation signals. The vector contains a neomycin resistance gene controlled by the SV40
promoter (P SV40 e) that allows selection of stably transfected eukaryotic cells using G418. An additional bacterial (Kan R) promoter drives
the expression of the same gene encoding for kanamycin resistance in E. coli.
