General description
The p3XFLAG-CMV™-9 Expression Vector is a 6.4 kb derivative of pCMV5 used to establish transient or stable expression of secreted N-terminal 3XFLAG™ fusion proteins in mammalian cells. The vector encodes three adjacent FLAG?epitopes (Asp-Tyr-Lys-Xaa-Xaa- Asp) upstream of the multiple cloning region. This results in increased detection sensitivity using ANTIFLAG M2 antibody. The third epitope includes the enterokinase recognition sequence, allowing cleavage of the 3XFLAG peptide from the purified fusion protein.
p3XFLAG-CMV-9 expression vector is a shuttle vector for E. coli and mammalian cells. Efficiency of replication and genomic integration is optimal when using an SV40 T antigen expressing host, such as COS cells. A related vector, p3XFLAG-CMV-3, has been used for stable transfection of HEK 293 cells. Efficiency of replication and genomic integration is optimal when using an SV40 T antigen-expressing host.
The p3XFLAG-CMV-7-BAP Control Plasmid is a 6.2 kb derivative of pCMV5 used for transient intracellular expression of N-terminal 3XFLAG bacterial alkaline phosphatase fusion protein in mammalian cells. The vector encodes three adjacent FLAG epitopes (Asp-Tyr-Lys-Xaa-Xaa-Asp) upstream of the multiple cloning region. This results in increased detection sensitivity using ANTI-FLAG M2 antibody. The third FLAG epitope includes the enterokinase recognition sequence, allowing cleavage of the 3XFLAG peptide from the purified fusion protein.

Components
- p3XFLAG-CMV™-9 Expression Vector 20 μg (E4276) is supplied as 0.5 mg/ml in 10 mM Tris-HCl (pH 8.0) with 1 mM EDTA.
- p3XFLAG-CMV™-7-BAP Control Plasmid 20 μg (C7472) is supplied as 0.5 mg/ml in 10 mM Tris-HCl (pH 8.0) with 1 mM EDTA.
Principle
The promoter-regulatory region of the human cytomegalovirus drives transcription of FLAG®-fusion constructs. The preprotrypsin leader sequence precedes the FLAG® sequence. The aminoglycoside phosphotransferase II gene (Neo-r) confers resistance to aminoglycosides such as G418 allowing for selection of stable transfectants.

Recent studies revealed that two novel interleukin (IL)-12-related cytokines, IL-23 and IL-27, have potent antitumor activities. However, the antitumor effects were mainly evaluated in relatively highly immunogenic tumors and have not been fully evaluated against nonimmunogenic or poorly immunogenic tumors.
