PREPARATIVE PURIFICATION PROCESS FOR HUMAN FURIN

Recombinant truncated human furin was expressed in CHO cells and concentrated approximately 50-fold by ultrafiltration and diafiltration. The concentrate was purified by column chromatography on Capto-MMC(TM) resulting in a 30-50 fold purification factor and a yield of at least 60%. The at least 20%...

More Information
Summary:Recombinant truncated human furin was expressed in CHO cells and concentrated approximately 50-fold by ultrafiltration and diafiltration. The concentrate was purified by column chromatography on Capto-MMC(TM) resulting in a 30-50 fold purification factor and a yield of at least 60%. The at least 20% pure preparation obtained after Capto-MMC(TM) chromatography had already a purification degree allowing on-column maturation of pro-VWF. Then an additional Arginine Sepharose chromatography purification was carried out. This two column process for purification of truncated human furin resulted in an almost pure furin preparation with a specific activity of approximately 290,000 U furin/mg protein and a yield of about 50%.
