WebFor your flag elution, do you have a 1x or a 3x flag-tagged protein? 3x flag tagged proteins are very poorly eluted with flag peptide. If you have a 1x flag-tagged protein, are you eluting with a 1x or a 3x flag peptide? An alternative method of elution is 2M MgCl2. It is possible that when you tried to elute your protein with the acidic ...
