Application

For purification of N-terminal FLAG fusion proteins. Since binding is Ca²⁺-dependent, proteins can be eluted with a buffer containing EDTA, as well as by the standard methods using either FLAG peptide or glycine-HCl buffer, pH 3. ANTI-FLAG M1 does not bind to Met-FLAG fusion proteins, so this resin is not appropriate for purifying unprocessed, cytoplasmically expressed fusion proteins.Affinity gel is for calcium mediated purification of N-terminal FLAG fusion proteins.immunoprecipitation (IP): suitableElution - FLAG peptide, Glycine, pH 3.5 EDTABrowse additional application references in our FLAG^® Literature portal.

Features and Benefits

Typically purify fusion proteins from crude lysates to single band purity in just one chromatography step. Fusion protein may be eluted from affinity resin by mild elution with EDTA. A solution of FLAG peptide can be used for gentle, non-denaturing elution of FLAG fusion proteins.
