RFC12 FLAG Tag Head Domain

This is a RFC12 compatible version of BBa_T2004. It is a FLAG tag head domain meant for n-terminal fusions.

Usage and Biology

The FLAG tag is a common epitope purification/detection method. Unlike c-myc tagging, flag tagging yields high enough yields and purity to be used for purification as well as detection, but the same problems with a non-regenerative matrix and low pH elution still apply. Elution with EDTA is also possible.

The tag can be cleaved off by enterokinase after the c-terminal lysine.

Common tag information:

  • Protein Sequence: DYKDDDDK
  • Matrix: Monoclonal Antibody
  • Yield/Purity: Fairly low yields, >90% purity
  • # Steps: One step
  • Fusion Location: N-terminus
  • Affects Function?: Tag will likely not, but a low pH elution may.
