3x DYKDDDDK Tag（Cat No.:I044185）is a synthetic peptide featuring three tandem repeats of the DYKDDDDK epitope, commonly known as the FLAG® tag. This sequence is extensively used in recombinant protein research to facilitate purification, detection, and localization of tagged proteins. The triplet configuration significantly enhances antibody-binding affinity, improving the efficiency of immunoassays such as Western blotting, immunoprecipitation, and ELISA. Compatible with a variety of expression systems, the 3x FLAG tag is highly valued for its small size, low immunogenicity, and strong specificity, making it ideal for sensitive and precise protein analysis.
