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.

Vector Maps and Sequences

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.
