Flag tag protein purification protocol
WebTo compare the responses of the Q-beads to those of the conventional Q-body, we generated Q-bodies as follows: 25 μL of anti-FLAG M2 monoclonal antibody beads were added to the eluent after His-tag purification and incubated at 25 °C. After 1 h, the beads were washed three times with 1 mL of PBS. WebThe FLAG tag is just an octapeptide that is recognized by the anti-FLAG antibody. The antibody is presumably bound to the agarose and is not being boiled. The anti-FLAG agarose should still...

Membrane proteins are usually purified as protein-lipid-detergent complexes. The solubility of the complexes in an aqueous environment allow the application of essentially the same separation techniques as used for water-soluble proteins. The main difference is that the purification of membrane proteins is ...
WebThe FLAG Expression System is an established way to express, purify and detect recombinant fusion proteins. FLAG and 3xFLAG have proven utility in numerous applications such as Western blotting, immunocytochemistry, immunoprecipitation, flow cytometry, protein purification, and in the study of protein-protein interactions, cell … WebThe Flag®-tag can be used for the purification of any recombinant protein fused to the Flag®-tag, using agarose resins or magnetic beads that are coupled to an anti-Flag® antibody. Even though high protein yields cannot be achieved with the Flag®-tag, it is mostly recommended to use the Flag® for membrane protein purification.
