pSF-CAG-Renilla (OG508) CAG Luciferase Reporter Plasmid

Product Code: OG508R1
Product Code: OG508C1
Product Code: OG508G1

Product Description

This plasmid vector contains the Renilla luciferase gene driven by the CAG promoter (a composite promoter containing the CMV enhancer, chicken beta actin promoter and rabbit beta globin intron)

Plasmid Information

Product Name: pSF-CAG-Renilla

Product Code: OG508

Size (bp): 6262 bp

Bacterial Antibiotic Selection: KanR

Origin and Compatibility: pUC high copy derived from pBR322

Bacterial Copy Number: 500-700 per cell

Promoter: CAG synthetic mammalian promoter and Ubiquitin promoter / Chicken Beta Actin (CBA) promoter

Plasmid Purpose:

This Renilla luciferase reporter plasmid is designed for the expression of luciferase under the control of the CAG promoter. The CAG promoter exhibits high levels of expression in most mammalian cell types and can be used as an alternative the CMV promoter.

Promoter Expression Level:

This plasmid contains the mammalian CAG promoter which is a synthetic composite of the CMV immediate early enhancer followed by the CBA promoter and the rabbit beta globin intron. The Chicken beta actin contains a CpG island that can help to keep the promoter active for longer in stable culture when compared to the CMV promoter.

Transcription Termination:

This plasmid contains three alternative transcription terminators for mammalian bacterial and bacteriophage (T7) expression. This means that only the promoter needs to be changed to alter the expression system you are using. We sell multiple promoters that can be used in each of these systems. The presence of each terminator does not reduce expression in the alternative systems.

Cloning in a gene:

This plasmid contains a gene within the main multiple cloning site (NotI-ClaI). Any plasmid that we sell where the gene is this configuration will be located in the exact same position in relation to the start and stop codon of the gene. The only exceptions to this rule are fusions proteins where the fusion gene may be positioned at the front or end of the MCS to allow gene fusion.

By positioning all of our genes in the same location it allows them to be transferred between plasmids using the same cloning method and restriction sites regardless of the plasmid being used from our product range. Inserting a new gene into this plasmid should be easily possible using a range of standard restriction enzyme sites that flank the gene currently in the vector.

Multiple cloning site notes:

In the multiple cloning site there are two important restriction sites called BsgI and BseRI sites. These sites both cut the DNA at the same position and cleave the stop codon of the gene in the multiple cloning site in this plasmid thereby producing a TA overhang. This overhang is compatible with any of our peptide or reporter fusion tag plasmids also cut with either of these enzymes. This allows seamless C-terminal fusions to be made with the gene in this multiple cloning site using a single cloning step from our C-terminal peptide and reporter tag product range. Normally the easiest method is to clone the C-terminal tag from our other plasmid products into this plasmid using BsgI or BseRI and the downstream ClaI restriction site.

BseRI and BsgI sites are non-palindromic and cleave a defined number of bases away from their binding sites. This allows them to cut the upstream stop codon in the gene in this plasmid regardless of the gene sequence.
