Flag tag protein purification protocol
WebAffinity-tagged purification. In two-step affinity-tagged protein purification, a protein is first purified by affinity chromatography, then desalted. In some medium pressure chromatography systems, such as the NGC medium pressure chromatography systems, these two steps can be automated. Web13. Elute the FLAG-tagged protein from the affinity resin by incubating the resin at 30°C for 15 minutes in lysis buffer containing 0.25 mg/mL “3xFLAG” peptide. Shake at 950 rpm. 14. Spin down sample (9000 rpm, 2 min) and transfer eluate to fresh 1.5 mL Axygen tube. Repeat step 13 and collect eluate into same tube as first. 15.
