The FLAG® peptide (Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys or DYKDDDDK) is intended for immunoaffinity chromatography to allow elution under non-denaturing conditions by competitive elution with excess of free FLAG® Peptide.

Product Details

DYKDDDDK (FLAG®) Peptide - 000-000-383
synthetic FLAG® peptide, ddddk peptide, dykddddk peptide, Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys, control peptide, blocking peptide, DDK, FLAG

Target Details

Greater than 90% specific peptide by HPLC and MS.

Application Details

The FLAG® peptide was tested by SDS-PAGE. A working concentration of 500 μg/mL for triple FLAG® peptide is typically used for competitive elution of FLAG® containing proteins from anti-DYKDDDDK affinity gels (p/n 200-350-383). For use as a control in antibody-peptide competition assays (PCA) use the peptide at 1.0 µg per 1.0 µl of antibody/antiserum in per assay. See anti-DYKDDDDK FLAG® affinity gel PROTOCOL for specific instructions for use.
