载体简介
系统介绍 The Vivid Colors Fluorescent Protein Gateway Destination Vectors allow you to quickly and easily fuse a protein of interest to the widely used and well-characterized fluorescent proteins from the jellyfish Aequorea victoria (1,2) using the pcDNA 6.2 Gateway mammalian expression vector. These powerful Gateway Technology vectors contain the next-generation EGFP, Emerald Green Fluorescent Protein (EmGFP), or the popular Yellow Fluorescent Protein (YFP) for simple, non-invasive detection of recombinant protein. Both fluorescent proteins have been humanized for optimal mammalian expression (3). In addition, the Vivid Colors pcDNA 6.2 Fluorescent Protein Gateway Vectors offer: CMV promoter for high-level expression of the recombinant fluorescent fusion protein Options to fuse EmGFP or YFP to the N- and C-terminus of your protein Vivid Colors pcDNA6.2/EmGFP and YFP-DEST vectors combine the ease and flexibility of Gateway recombination based cloning with the brightness of Emerald Green Fluorescent Protein (EmGFP) and Yellow Fluorescent Protein (YFP) derived from Aequorea victoria GFP. Users can easily make an EmGFP or YFP N- or C-terminally tagged mammalian expression clone by performing an LR recombination reaction between a Gateway entry vector containing the gene of choice and a Vivid Colors pcDNA6.2/EmGFP or YFP-DEST Gateway Vector. After transfection of the expression clone into mammalian cells, the fluorescent-tagged protein of interest can be identified by fluorescence detection methods for localization experiments. The protein of interest can also be analyzed by Western blot. The Vivid Colors pcDNA6.2/EmGFP or YFP-DEST Gateway Vectors are supplied with either an N- or C-terminal tagged EmGFP or YFP/GW/CAT plasmid that serves as a control for transfection efficiency of the expression clone into the target cells, as well as a control for expression of the gene of interest. 载体特征 pcDNA6.2/EmGFP-DEST载体含有以下元件： Human cytomegalovirus immediate-early (CMV) promoter/enhancer for high-level expression in a wide range of mammalian cells Two recombination sites, attR1 and attR2, downstream of the CMV promoter for recombinational cloning of the gene of interest from an entry clone Emerald Green Fluorescent Protein (EmGFP) or Yellow Fluorescent Protein (YFP) derived from Aequorea victoria GFP for N- or C-terminal fusion to the gene of interest for fluorescent detection The V5 epitope tag for detection of recombinant protein using Anti-V5 antibodies (optional on N-terminal fusion vectors only) CAT gene located between the two attR sites for counterselection The ccdB gene located between the two attR sites for negative selection The Herpes Simplex Virus thymidine kinase polyadenylation signal for proper termination and processing of the recombinant transcript f1 intergenic region for production of single-strand DNA in F plasmid-containing E. coli SV40 early promoter and origin for expression of the Blasticidin resistance gene and stable propagation of the plasmid in mammalian hosts expressing the SV40 large T antigen Blasticidin resistance gene for selection of stable cell lines The pUC origin for high copy replication and maintenance of the plasmid in E.coli The ampicillin (bla) resistance gene for selection in E. coli 绿色荧光蛋白(GFP) Green Fluorescent Protein (GFP) is a naturally occurring bioluminescent protein derived from the jellyfish Aequorea victoria (Shimomura et al., 1962). GFP emits fluorescence upon excitation, and the gene encoding GFP contains all of the necessary information for posttranslational synthesis of the luminescent protein. GFP is often used as a molecular beacon because it requires no species-specific cofactors for function, and the fluorescence is easily detected using fluorescence microscopy and standard filter sets. Commonly, GFP is fused to a protein of interest, and upon expression, the localization of the fusion protein can be detected in cells. GFP can also function as a reporter gene downstream of a promoter of interest. Modifications have been made to the wild-type GFP to enhance its expression in mammalian systems. These modifications include amino acid substitutions that correspond to the codon preference for mammalian use, and mutations that increase the brightness of the fluorescence signal, resulting in “enhanced” GFP (Zhang et al., 1996).Mutations have also arisen or have been introduced into GFP that further enhance and shift the spectral properties of GFP such that these proteins will emit fluorescent color variations (reviewed in Tsien, 1998). The Emerald GFP (EmGFP) and Yellow Fluorescent Protein (YFP) are such variants of enhanced GFP.
