稳定性: 瞬表达 或 稳表达 组成型/诱导型: 组成型 病毒/非病毒:非病毒pNFkB-‐DD-‐AmCyan1载体质粒图谱和多克隆位点信息pNFkB-DD-AmCyan1载体描述pNFkB-DD-AmCyan1 is a reporter vector that allows you to monitor NFkB activation in mammalian cells. The vector contains an NFkB enhancer element (composed of four tandem copies of the NFkB consensus binding sequence; 1) upstream of a minimal TA promoter (PTA), which consists of the TATA box from the herpes simplex virus thymidine kinase (HSV-TK) promoter. The vector encodes the reporter protein DD-AmCyan1, a ligand-dependent, destabilized cyan fluorescent protein that minimizes background fluorescence from leaky promoters.AmCyan1 is a human codon-optimized variant of the wild-type Anemonia majano cyan fluorescent protein (AmCyan) that exhibits enhanced emission characteristics (excitation and emission maxima: 458 and 489, respectively; 2, 3). DD-AmCyan1 is a modified version of AmCyan1 that is tagged on its N-terminus with the ProteoTuner destabilization domain (DD; 4). The presence of this destabilization domain causes rapid, proteasomal degradation of the fluorescent fusion protein; however, when the membrane permeant ligand Shield1 is added to the medium, it binds to the destabilization domain and protects the fusion protein from degradation.In the absence of Shield1, the destabilization domain causes the degradation of any DD-AmCyan1 reporter protein produced prior to promoter activation, thus reducing background fluorescence. In order to analyze NFκB activation, an inducer of choice is added to the medium along with the Shield1 stabilizing ligand, which effectively stabilizes the reporter protein, allowing it to accumulate. As a result, only the reporter molecules expressed during promoter induction will contribute to the fluorescence signal, providing a considerably higher signal-to-noise ratio than thatobtained with non-destabilized or constitutively destabilized reporter systems. The high signal-to-noise ratio also allows the monitoring of NFκB activation during discrete windows of time when Shield1 is added to the cell medium for discrete periods of time.The vector backbone contains an SV40 origin for replication in mammalian cells expressing the SV40 large T antigen, a pUC origin of replication for propagation in E. coli, and an f1 origin for single-stranded DNA production. A neomycin-resistance cassette (Neor) allows stably transfected eukaryotic cells to be selected using G418 (5). This cassette consists of the SV40 early promoter, a Tn5 kanamycin/neomycin resistance gene, and herpes simplex virus thymidine kinase (HSV TK) polyadenylation signals. A bacterial promoter upstream of the cassette expresses kanamycin resistance in E. coli.UseThe pNFkB-DD-AmCyan1 Reporter vector, available as part of the NFkB DD Cyan1 Reporter System (Cat. No. 631083), can be used to monitor NFkB activation in live cells as well as in vivo. pNFkB-DD-AmCyan1 Reporter can be transfected into mammalian cells using any standard transfection method. If required, stable transfectants can be selected using G418.Propagation in E. coliRecommended host strains: DH5α, HB101, and other general purpose strains. Single-stranded DNA productionrequires a host containing an F plasmid such as JM109 or XL1-Blue.Selectable marker: plasmid confers resistance to kanamycin (50 µg/ml) in E. coli hosts.E. coli replication origin: pUCCopy number: highPlasmid incompatibility group: pMB1/ColE1Excitation and emission maxima of AmCyan1Excitation maximum = 458 nmEmission maximum = 489 nm其他哺乳动物表达载体:pCHO1.0 pBApo-CMV-Pur pOPRSVIpcDNA3.1/His C pcDNA5/FRT/V5-His-TOPO pREP4pcDNA3.1/His B pcDNA5/FRT/TO-TOPO pDual-GCpcDNA3.1/His A pcDNA5/TO pBK-RSVpIRESpuro3 pcDNA5/FRT/TO pBK-CMVpIRES2-EGFP pcDNA5/FRT pBI-CMV4pTT5 pFLAG-CMV2 pcDNA4/TO/Myc-His/LacZ pNFkB-DD-tdTomato pcDNA3.1/CT-GFP-TOPO pOPI3CATpBI-CMV5 pcDNA3.1/NT-GFP-TOPO pGene/V5-His B pSEAP2-Basic pOptiVEC-TOPO pSwitchpSEAP2-Control pCMV-MEKK1 pCMVLacIpBI-CMV3 pCMV-MEK1 pVgRxRpBI-CMV2 pCMV-PKA pINDpBI-CMV1 pcDNA6.2/nTC-Tag-DEST pTRE3G-LucpNFκB-MetLuc2-Reporter pcDNA6.2/cTC-Tag-DEST pTRE3GpCRE-MetLuc2-Reporter pcDNA3.2/V5/GW/D-TOPO pTRE2-hygropAcGFP1-Actin pcDNA6.2/V5/GW/D-TOPO pTRE-TightpAcGFP1-N In-Fusion Ready pcDNA6.2/nGeneBLAzer-GW/D-TOPO pTK-hygpAcGFP1-C3 pcDNA6.2/C-YFP-DEST pTet-OnpAcGFP1-C pcDNA6.2/cGeneBLAzer-DEST pTet-OffpAcGFP1-p53 pcDNA6/V5-His A pTet on advanced pAcGFP1-Mito pcDNA6/V5-His B pRevTREpAcGFP1-Mem pcDNA6/V5-His C pRevTet-OnpAcGFP1-Lam pcDNA6/myc-His C pRevTet-OffpAcGFP1-Golgi pcDNA6/myc-His A pCMV-Tet3GpAcGFP1-F pcDNA6/myc-His B pTRE2pAcGFP1-Hyg-C1 pcDNA6.2/nGeneBLAzer-DEST pBD-NF-κBpAsRed2-N1 pcDNA4/HisMax-TOPO pCMV-ADptdTomato-N1 pcDNA6.2/nLumio-DEST pCMV-BDpCMV-tdTomato pcDNA6.2/cLumio-DEST pBIND-Id ControlpCRE-DD-tdTomato pcDNA4/myc-His C pBINDpCMV-DsRed-Express2 pcDNA4/HisMax C pG5 luciferasepEF1α-tdTomato pcDNA4/HisMax A pACT-MyoDpCRE-hrGFP c-Flag pcDNA3 pACTptdTomato-C1 pcDNA4/HisMax B pCMV-SPORT6 pAsRed2-C1 pcDNA4/myc-His B pGL4.13pGL3-Promoter pcDNA4/myc-His A pGL4.19pGL3 basic pcDNA4/His C pGL4.26pAcGFP1-C2 pcDNA4/His B pGL4.20pAcGFP1-C1 pcDNA4/His A pGL4.29pAcGFP1-N3 pcDNA6/TR pGL4.30pAcGFP1-N2 pcDNA4/TO/Myc-His A pGL4.27pAcGFP1-N1 pcDNA4/TO pGL4.75pAcGFP1-C In-Fusion Ready pcDNA4/TO/Myc-His B pGL4.10pCRE-DD-AmCyan1 pcDNA4/TO/Myc-His C pGRN145pNFkB-DD-AmCyan1 pcDNA3.3-TOPO pSecTag2 A pDsRed2-Bid pBudCE4.1 pEBVHis B pDsRED2-Mito pFLAG-CMV-4 pEBVHis ApDD-AmCyan1 Reporter pFLAG-CMV-3 pCMV-Tag 3C pAmCyan1-N1 pFLAG-CMV-2 pCMV-Tag 3A pAmCyan1-C1 pFLAG-CMV-5a pCMV-Tag 3BpEF1α-IRES-DsRed-Express2 p3XFLAG-CMV-9 pCMV-Tag 5CpEF1α-DsRed-Monomer-N1 p3xFLAG-CMV-10 pCMV-Tag 5A pDsRED-Monomer-N1 p3XFLAG-CMV-8 pCMV-Tag 4A pDsRed-Express-N1 p3XFLAG-CMV-7.1 pCMV-Tag 5Bp3XFLAG-CMV-7 pDsRed-Monomer-N In-Fusion Ready pCMV-Tag 4B pDsRed-Express-C1 p3XFLAG-CMV-13 pCMV-Tag 2C pIRES2-ZsGreen1 p3XFLAG-CMV-14 pCMV-Tag 2B pDsRed-Express2-C1 plRES2-ZsGreen1 pCMV-Tag 2A pDsRed-Express2-N1 pBApo-EF1α-pur pCMV-LacZpEF1α-DsRed-Express2 pBApo-EF1α-neo pCMV-MycpIRES2-DsRed-Express pBApo-CMV pEF1α-IRES-AcGFP1 pIRES2-DsRed-Express2 pBApo-CMV-neo pEF1α-IRES-ZsGreen1 pIRES-hrGFP-1a pIRES-EGFP pEF1α-AcGFP1-N1 pIRESneo2 pIRESneo3 pIRES2-DsRed2 pIRESneo pDsRed-Monomer pIRES2-AcGFP1 pIREShyg3 pIRES。

Although translation initiation of eukaryotic mRNAs occurs almost exclusively at the 5' cap, the IRES allows ribosomes to bind and initiate translation at a second, internal location. Thus, two proteins areexpressed simultaneously from the same bicistronic mRNA transcript.Clontech's pIRES Vector contains two multiple cloning sites flanking the central IRES for you to clone and express two genes of interest.pIRES Vectors Containing Antibiotic Selection MarkersThe pIRES Selection Vectors pIRESpuro3, pIREShyg3, pIRESneo3, and pIRESbleo3 each contain a multiple cloning site located upstream of the IRES from which a selection marker is expressed. Because your gene of interest and a selection marker are translated from a single RNA, you can be certain that nearly 100% of the colonies that are resistant to puromycin, hygromycin, G418, and bleomycin also express your protein of interest.All IRES Selection Vectors contain a partially disabled IRES which reduces the efficiency of translation initiation for the selection marker relative to that of the cloned gene, and allows preferential selection of cells expressing high levels of your protein of interest (3).Bicistronic (IRES) Fluorescent Protein Expression VectorsSimilarly, fluorescent protein-containing IRES vectors allow coexpression of your target protein and a fluorescent protein.Successfully transfected target cells are easily identified by fluorescence microscopy or flow cytometry. The are several options for different fluorescent proteins, which include mCherry, ZsGreen1, and tdTomato (pLVX-IRES Vectors) and AcGFP1, DsRed2, and DsRed-Express (pIRES2 Vectors).FeaturesTranslate your gene of interest and an antibiotic resistance marker or fluorescent protein from a single mRNAQuickly identify cells expressing your protein of interest at high levelsBicistronic expression allows faster, better stable clone selectionChoice of vectors enables screening via antibiotic selection, fluorescence microscopy, or flow cytometryApplicationsRapidly select stable clones that show high-level expression of your target protein Identify transfected cells by antibiotic selection, fluorescence microscopy, or flow cytometryReferencesJackson, R.

实验原理和应用的介绍
关于转染(transfection) 关于脂质体转染法 关于荧光蛋白
关于转染(transfection)
关于荧光蛋白(reporter gene)
绿色萤光蛋白(green fluorescent protein),简称GFP, 最早在一种学名Aequorea victoria的水母中发现。其基因 所产生的蛋白质是一个由238个氨基酸残基组成的单链 , 在蓝色波长范围的光线激发下,会发出绿色荧光。
GFP的化学性质相当稳定,其变性需要在90℃,或pH<4 或pH>12的条件下用6mollL盐酸胍处理。
哺乳动物细胞表达重组蛋白
哺乳动物细胞大规模生产重组蛋白的关键之处
表达载体 改进表达载体,提高表达水平和产量 分泌表达 下游纯化
宿主细胞 新型细胞株的建立
培养工艺
一、 真核表达载体
人工构建的哺乳动物细胞表达载体为穿梭载体,含: 原核DNA序列:大肠杆菌复制子及抗生素抗性基因,便于 载体在原核细胞中扩增和大量制备。 转录相关元件:哺乳动物细胞中有效转录的启动子和增强子 元件,以及终止子和加polyA信号序列。。 翻译相关元件:有效的mRNA翻译信号 其它:视实验需要加入标志基因、内含子、内部核糖体进入 位点等。
利用代谢工程,改进培养工艺,降低生产成本
采用无血清/无蛋白培养基(SFM/PFM)来降低细胞培养和产 品纯化的成本。双无培养基
但SFM/PFM缺乏生长刺激因子、黏附因子、扩展因子以及其 他细胞生长存活所必需的成分,在培养过程中细胞常表现出活力降 低、贴壁性差等现象,进而导致分泌目的蛋白的能力下降。
通过将生长刺激因子、黏附因子基因导入CHO细胞中,让 CHO细胞本身提供其自身生长所需要的成分,使其能在SFM/ PFM中生长良好。
抑制细胞凋亡,延长培养周期
细胞在大规模培养初期, 目的蛋白的表达和细胞的增殖速率呈正 相关。
但当反应器中细胞的密度达到饱和后,细胞继续增殖会导致养分 和氧的大量消耗以及乳酸、氨等有毒代谢产物的大量积累,细胞逐渐 凋亡,重组蛋白表达量逐渐降低。
哺乳动物细胞大规模培养生产重组蛋白中, 常用的细胞系有 中国仓鼠卵巢细胞(CHO) 人胚肾细胞HEK293
中国仓鼠卵巢细胞(CHO的优势 遗传背景清楚,生理代谢稳定 与人的亲缘关系接近,外源蛋白修饰准确 基因转移和载体表达系统完善 耐受剪切力,便于大规模培养 被美国FDA确认为安全的基因工程受体细胞

The coding sequence of the AcGFP1 gene contains silent base changes, which correspond to human codon-usage preferences (1). The MCS in pAcGFP1-N1 is between the immediate early promoter of CMV (PCMV IE) and the AcGFP1 coding sequences. Genes cloned into the MCS will be expressed as fusions to the N-terminus of AcGFP1 if they are in the same reading frame as AcGFP1 and there are no intervening stop codons. SV40 polyadenylation signals downstream of the AcGFP1 gene direct proper processing of the 3' end of the AcGFP1 mRNA. The vector backbone also contains an SV40 origin for replication in mammalian cells expressing the SV40 T antigen. A neomycin-resistance cassette (Neor), consisting of the SV40 early promoter, the neomycin/kanamycin resistance gene of Tn5, and polyadenylation signals from the Herpes simplex virus thymidine kinase (HSV TK) gene, allows stably transfected eukaryotic cells to be selected using G418. A bacterial promoter upstream of the gene expresses kanamycin resistance in E. coli. The pAcGFP1-N1 backbone also provides a pUC origin of replication for propagation in E. coli and an f1 origin for single-stranded DNA production.Fusions to the N terminus of AcGFP1 retain the fluorescent properties of the native protein allowing the localization of the fusion protein in vivo . The target gene should be cloned into pAcGFP1-N1 so that it is in frame with the AcGFP1 coding sequences, with no intervening in-frame stop codons. The inserted gene should include the initiating ATG codon. The recombinant AcGFP1 vector can be transfected into mammalian cells using any standard transfection method. If required, stable transformants can be selected using G418 (2). pAcGFP1-N1 can also be used simply to express AcGFP1 in a cell line of interest (e.g., as a transfection marker). Propagation in E. coliSuitable host strains: DH5α, HB101 and other general purpose strains. Single-stranded DNA production requiresa host containing an F plasmid such as JM101 or XL1-Blue.Selectable marker: plasmid confers resistance to kanamycin (30 μg/ml) to E. coli hosts.E. coli

Post-translation of this farnesylation signal targets AcGFP1-F to the inner leaflet of the plasma membrane. AcGFP1 is derived from Aequorea coerulescens. When AcGFP1-F is expressed in mammalian cell cultures, green fluorescent cells can be detected by either fluorescence microscopy or flow cytometry 12–16 hr after transfection (excitation maximum = 475 nm; emission maximum = 505 nm, respectively). The AcGFP1 coding sequence is human-codon-optimized for increased translation efficiency in mammalian cells (3). SV40 polyadenylation signals downstream of the AcGFP1-F gene direct proper processing of the 3’ end of the AcGFP1-F mRNA. The vector backbone also contains an SV40 origin for replication in mammalian cells expressing the SV40 T-antigen. A neomycin resistance cassette (Neor), consisting of the SV40 early promoter, the neomycin/kanamycin resistance gene of Tn5, and polyadenylation signals from the herpes simplex virus thymidine kinase (HSV TK) gene, allows stably transfected eukaryotic cells to be selected using G418. A bacterial promoter upstream of this cassette expresses kanamycin resistance in E. coli. The pAcGFP1-F backbone also provides a pUC origin of replication for propagation in E. coli and an f1 origin for single-stranded DNA production.pAcGFP1-F is designed for use as a plasma membrane marker, as well as a cotransfection marker. Because it remains attached to the plasma membrane, it can be detected by fluorescence microscopy in permeabilized cells after ethanol fixation (4). The vector can be transfected into mammalian cells using any standard transfection method. If required, stable transformants can be selected using G418 (5). Propagation in E. coliSuitable host strains: DH5a, HB101, and other general purpose strains. Single-stranded DNA productionrequires a host containing an F plasmid such as JM109 or XL1-Blue.Selectable marker: plasmid confers resistance to kanamycin (50 μg/ml) in E. coli hosts.E. coli replication origin: pUC; copy number: highReferences1.
