General description
The pFLAG-CTC™ Expression Vector is a 5.3 kb E. coli expression vector used for cytoplasmic expression of a properly inserted open reading frame as a C-terminal FLAG® fusion protein. The FLAG epitope is a small, hydrophilic 8 amino acid tag (DYKDDDDK) that provides for sensitive detection and high quality purification using ANTI-FLAG products.
C-terminal FLAG fusion proteins may be purified using Monoclonal ANTI-FLAG M2, Catalog Number F3165, and ANTI-FLAG M2 Affinity Gel, Catalog Number A2220.
The pFLAG-CTS-BAP Control Plasmid is a 6.7 kb vE. coli plasmid used for efficient and controlled periplasmic expression of C-terminal FLAG-BAP fusion protein.

Components
- pFLAG-CTC™ Expression Vector 10 μg (E5394) is supplied as 0.5 mg/ml in 10 mM Tris-HCl (pH 8.0) with 1 mM EDTA.
- pFLAG-CTS™-BAP Control Plasmid 1 μg (P7707) 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 strong tac promoter (a hybrid of the trp and lac promoters from E.coli) drives transcription of ORF-FLAG fusion constructs. Control of transcription is regulated by the presence of the lacO sequences and inclusion of the lac repressor gene (lacI) on the plasmid.

mRNA stability is one among many parameters that can potentially affect the level of recombinant gene expression in bacteria. Blocking of the entire prokaryotic transcription machinery by addition of rifampicin is commonly used in protocols for analysis of mRNA stability.
