General description

Recommended working concentration is 100 μg/ml for elute 3X FLAG fusion proteins from the ANTI-FLAG® M2 affinity gel.
The 3X FLAG Peptide is a synthetic peptide of 23 amino acid residue. The Asp-Tyr-Lys-Xaa-Xaa-Asp motif is repeated three times in the peptide. Eight amino acids at the C-terminus make up the classic FLAG sequence (Asp-Tyr-Lys-Asp-Asp-Asp-Asp-Lys).

Application

For use in competitive elution of 3X FLAG® fusion proteins from the ANTI-FLAG® M2 monoclonal antibody (F1804) in solution or bound to agarose on the ANTI-FLAG® M2 agarose affinity gel (A2220). This is achieved by Affinity Chromatography. For the gentle elution of 3X FLAG fusion proteins from the ANTI-FLAG® M2 affinity gels. 1X FLAG Peptide (F3290) will not elute 3X FLAG fusion proteins from ANTI-FLAG® affinity gels.

During epithelial-to-mesenchymal transitions (EMTs), cells disassemble cadherin-based junctions to segregate from the epithelia.
