载体简介
pMetLuc2-Reporter载体描述
pMetLuc2-Reporter is a promoter reporter vector that allows the analysis of promoter function in cell-based assays. The vector encodes a sequence-optimized, secreted luciferase from the marine copepod Metridia longa. The 24 kDa Metridia luciferase (MetLuc) reporter protein
contains a 17 amino acid, N-terminal signal peptide that allows efficient secretion of the reporter (1). When a functional promoter is cloned into the MCS, located upstream of the MetLuc reporter gene, MetLuc is expressed and secreted into the medium surrounding the transfected cells.
SV40 polyadenylation signals downstream of the MetLuc gene direct proper processing of the 3' end of the MetLuc mRNA. 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. This cassette consists of the SV40 early promoter, the Tn5 kanamycin/neomycin resistance gene, and polyadenylation signals from the herpes simplex virus thymidine kinase (HSV TK) gene. The vector also contains a synthetic transcription blocker (TB), composed of adjacent polyadenylation and transcription pause sites, that reduces background readthrough transcription (2). A bacterial promoter (PKanr) upstream of the cassette allows kanamycin resistance in E. coli.
The pMetLuc2-Reporter vector is used to monitor the activity of promoters cloned into the MCS, located upstream of the Metridia longa luciferase coding sequence. Upon induction, functional promoters will drive the expression of secreted luciferase, while nonfunctional promoters will not. The presence of the luciferase can be easily detected by adding luciferase substrate to a small aliquot of the culture medium and analyzing the sample in a luminometer. Promoter function can be quantified by the relative intensity of the bioluminescent signal.
The pMetLuc2-Reporter Vector can be transfected into mammalian cells using any standard transfection method. Stable transfectants can be selected using G418 when required (3).
Propagation in E. coli
Suitable host strains: DH5α, HB101, and other general purpose strains. Single-stranded DNA production requires
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
Plasmid incompatibility group: pMB1/Col E1

文献和实验相关实验
啦！ 呵呵，以前看到过有人把NOTCH1的intracellular domain连上GAL4-VP16，然后共转UAS-Reporter。相当于一个直接结合的报告基因系统。UAS-Reporter可以改造pG5Luc载体。 NLS序列在pACT的vp16AD或者pGADT7的gal4AD的上游处，都是SV40NLS，说明书上就有。 呵呵，我不知道常用载体里有没有不带NLS的GAL4序列。GAL4-UAS系统思路及经典文献可以参考93年development
的吗？我看有的文献说看转了片段的荧光素酶载体的活性，如果活性低说明miRNA与靶基因相互作用，这个和您说的方法是一种吗？ 另外，插入片段的psiCHECK2-Dual luciferase reporter vector、microRNA的precursor（Gain of function)和Inhibitors（Loss of function)三者必须都要吗？直接通过共转microRNA的precursor与插入片段的psiCHECK2-Dual luciferase
载体操作中最常用的几个概念： 1. The lac Z gene may be used as a simple "reporter" gene, separated from its natural promoter. For example, we might put the lac Z gene in front of a mammalian promoter
