This vector is for the production of kappa antibody light chains for rat (Rattus rattus). It has been engineered so that when the vector is cut with the restriction enzyme BseRI it produces an overhang from the first codon of the constant region. This allows antibody light chain variable regions to be seamlessly ligated into this vector to create full length rat kappa light chain antibody expression cassettes. As part of this vector range we also provide plasmids for the production of both human and mouse antibodies as well as vectors for the creation of Heavy IgG chain and Lambda light chain rat antibodies (named pSF-CMV-Rat-IgG HC and pSF-CMV-Rat-Lambda respectively)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.
