This affinity purified antibody is directed against the FLAG™ motif and is useful in determining its presence in various assays. This polyclonal anti-FLAG™ tag antibody detects over-expressed proteins containing the FLAG™ epitope tag. To date this antibody has reacted with all amino- terminal FLAG™ tagged proteins so far tested. In western blotting of bacterial extracts the antibody does not cross-react with endogenous proteins.

Target Information

DYKDDDDK tag, also known as FLAG tag, is a short peptide sequence that is 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 of the protein using anti-FLAG antibodies. The DYKDDDDK tag is widely used in molecular biology and biochemistry research, and has been employed in various applications, such as protein-protein interaction studies, protein expression analysis, and protein localization studies. The FLAG tag structure has been optimized for compatibility with the proteins it is attached to, in that it is more hydrophilic than other common epitope tags and therefore less likely to denature or inactivate proteins to which it is appended. FLAG is a registered trademark of Merck KGaA, Darmstadt, Germany.
