pDsRed2-ER是一種哺乳動(dòng)物表達(dá)載體，用于標(biāo)記活細(xì)胞內(nèi)質(zhì)網(wǎng)。DsRed2基因是按人的密碼子優(yōu)化過(guò)的野生型DsRed變體，可以更快的成熟和較低的非特異性聚集。
The vector encodes a fusion consisting of Discosoma sp. red fluorescent protein; the endoplasmic reticulum (ER) targeting sequence of calreticulin , fused to the 5' end of DsRed2; and the ER retention sequence, KDEL, 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.To drive expression of DsRed2, this vector contains the immediate early promoter of cytomegalovirus (PCMV IE). SV40 polyadenylation signals downstream of the DsRed2 gene direct proper processing of the 3'-end of the DsRed2 mRNA transcript. The vector also contains an SV40 origin for replication in any mammalian cell line that expresses the SV40 Tantigen, a pUC origin of replication for propagation in E. coli, and an f1 origin for single-stranded DNA production. A neomycin resistance cassette—consisting of the SV40 early promoter (PSV40e), the neomycin/kanamycin resistance gene of Tn5 (Neor/Kanr), and polyadenylation signals from the herpes simplex virus thymidine kinase (HSV TK poly A) gene— allows stably transfected eukaryotic cells to be selected using G418 . A bacterial promoter (P) upstream of this cassette drives expression of the gene encoding kanamycin resistance in E. coli.pDsRed2-ER can be introduced into mammalian cells using any standard transfection method. If required, stable transformants can be selected using G418 .
