A versatile cloning plasmid for the expression of genes in mammalian cells. This plasmid contains the multiple cloning site (MCS) from pUC18 however it has been modified slightly to accommodate some restriction sites in the SnapFastTM system. These changes are described in the full plasmid details PDF. The use of this MCS instead of the normal SnapFastTM vector MCS will limit the ability to use some of the inserts that we sell that immediately flank or are inserted within the standard MCS. This primarily includes N-terminal tags and signal peptides. This is because these inserts are flanked by restriction sites that are not compatible with the pUC18 MCS. Most other inserts should still be compatible with this plasmid.Promoter Expression Level:
This plasmid contains the mammalian CMV promoter to drive gene expression. We have tested all of our mammalian promoters in a range of cell types and CMV is consistently the strongest in those we have studied. However there are many reports of the CMV promoter demonstrating silencing by methylation in long-term culture. For this reason we stock a range of other promoters that are compatible with this plasmid and are available on request.
Please select the file type you require. For reference most cloning programs will import a .gb (Genbank) file and will show all of the plasmids features automatically when downloaded and imported.
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.
This vector contains a different multiple cloning site (MCS) from the standard SnapFast vector. The MCS is derived from pUC18. The order of the restriction sites in this vector are almost the same as in pUC18 however the sequence is not. The pUC18 MCS has also been modified as follows:
