Function
The FLAG tag serves as an affinity and detection tag that can be fused to recombinant proteins. It is recognized by anti-FLAG antibodies and affinity reagents for purification, immunoprecipitation, western blotting, immunofluorescence, flow cytometry, and ELISA.
Description
The FLAG tag is a short artificial peptide epitope widely used in recombinant protein expression, purification, detection, and localization studies. The canonical FLAG sequence is DYKDDDDK.
Biological role
Recombinant protein detection
Affinity purification
Immunoprecipitation
Protein localization studies
Research relevance
FLAG-tagged proteins are extensively used in molecular biology and protein expression systems because the tag is small, highly immunogenic, and generally does not interfere with protein folding or function.
Keywords
Epitope tag, Protein purification, Protein detection, Recombinant protein
Structure
The FLAG tag is a synthetic peptide epitope with the canonical amino acid sequence DYKDDDDK.
Function
FLAG serves as a molecular tag for detection, purification, and characterization of recombinant proteins.
Detection
FLAG-tagged proteins are commonly detected using anti-FLAG antibodies such as M1 and M2 clones in western blotting, ELISA, immunofluorescence, and immunoprecipitation assays.
Purification
FLAG affinity resins and magnetic beads enable rapid purification of FLAG-tagged proteins under native or denaturing conditions.
Research relevance
The FLAG tag is one of the most widely used epitope tags in molecular biology, biotechnology, and recombinant protein production.
