The pSF-CMV-NH2-PPT-3XFLAG expression vector is a 4.6 kb derivative of pSF-CMV-Amp for transient expression of secreted N-terminal 3XFLAG fusion proteins in mammalian cells. This vector encodes three FLAG epitopes in tandem (DYKDHDG-DYKDHDI-DYKDDDDK), which results in increased sensitivity when using the anti-FLAG M2 antibody (catalogue number F3165). The third epitope includes the enterokinase recognition sequence, allowing cleavage of the 3XFLAG peptide from the purified fusion protein. The preprotrypsin (PPT) leader sequence precedes the 3XFLAG sequence and directs secretion of the fusion protein into the culture medium. pSF-CMV-NH2-PPT-3XFLAG is a shuttle vector, containing both E. coli and SV40 origins of replication, for propagation in bacterial and mammalian cells. Efficiency of replication and genomic integration is optimal when using an SV40 T antigen expressing mammalian host. The promoter regulatory region of the human cytomegalovirus drives transcription of FLAG fusion constructs.
