Plasmid Purpose:

The Frosty Cyan Fluorescence Protein (FrCFP) is under regulatory control of the minimal CMV promoter in this plasmid giving low level expression of the FrCFP transgene in most types of mammalian cells. Positive or negative regulatory elements can be introduced upstream of the minimal promtoer using a specially-positioned MCS to endow your required responsiveness. For example transcription factor binding sites could be introduced to provide tissue-selective transgene expression. Similarly drug-responsive sites could be introduced to provide expression regulated by externally-applied drugs.

Promoter Expression Level:

This plasmid contains the minimal CMV immediate early promoter with a multiple cloning site immediately upstream that allows transcription factor binding sites to be inserted. This allows tissue specific or physiologically responsive promoters to be created.

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.

Intellectual Property Status

According to our IP-friendly policy this plasmid is sold free of reach-through rights and can be used to make commercial products. However the plasmid itself (or derivatives) cannot be sold.
