BD Pharmingen™ Red FP Vector - Peroxisome is a mammalian expression vector that encodes a fusion of the red fluorescent protein (FP)
from Discosoma sp. with the peroxisomal targeting signal 1 (PTS1), which encodes a tripeptide SKL that targets the red FP to the matrix of
peroxisomes. The PTS1 sequence is fused to the 3’-end of red 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 red FP open reading frame, and its sequence has been optimized
with human codons. The red FP fusion is expressed under the control of the immediate early promoter of cytomegalovirus (P CMV ie), and
its sequence is followed by downstream simian virus 40 (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.
