This expression plasmid contains the human IgG heavy chain constant region and has been designed to allow the seamless fusion of variable antibody fragments to create full length heavy chain expression constructs. The vector has been engineered to contain a BseRI restriction enzyme site upstream of the constant domain that when cleaved produces an overhang of the first two bases of the first codon of the constant region. This allows variable antibody fragments to be cloned upstream to create full length antibody genes. We also provide plasmids for human Kappa and Lambda light chain expression (termed pSF-CMV-HuKappa LC and pSF-CMV-HuLambda LC repectively). We also have a range of antibody expression plasmids for mouse and rat IgG heavy and light chains.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.
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.
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.
