Description

Flag-Tag represents a synthetic octapeptide consisting of the amino acid sequence DYKDDDDK, designed as a standardized epitope tag for protein purification, detection, and characterization in research applications. The peptide was developed to provide a small, hydrophilic tag that can be fused to proteins of interest without significantly affecting their structure or function. The Flag-Tag sequence is recognized by specific anti-Flag antibodies, enabling efficient immunoaffinity purification and detection of tagged proteins. The peptide’s design incorporates charged residues that enhance its hydrophilicity and accessibility for antibody binding while maintaining minimal impact on protein folding and function. Research applications include protein purification protocols, protein-protein interaction studies, and protein localization experiments in various biological systems. For research use only.
