Target Information

DYKDDDDK tag, also known as FLAG tag, is a short peptide sequence commonly used as a protein tag to facilitate protein purification, detection, and localization.
The tag consists of eight amino acids: Asp–Tyr–Lys–Asp–Asp–Asp–Asp–Lys.
It is often fused to the N- or C-terminus of a protein of interest, allowing for easy identification and isolation using anti-FLAG antibodies.
The DYKDDDDK tag is widely used in molecular biology and biochemistry research, including protein–protein interaction studies, protein expression analysis, and protein localization studies.
The FLAG tag structure has been optimized for compatibility with attached proteins, being more hydrophilic than other epitope tags and less likely to denature or inactivate target proteins.

FLAG is a registered trademark of Merck KGaA, Darmstadt, Germany.
