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.
