Human albumin purification: a modified and concise method

ABSTRACTBackground: Among different proteins of blood, albumin is considered a unique protein due to having special properties. Now, various protocols are used for the albumin purification worldwide, each of them has its own advantages and disadvantages. Meanwhile, a common method which is often used for the production of albumin is a combination of Cohn along with different types of chromatography. The aim of the present study was to create a concise and cost-effective albumin purification method by employing a conventional method with some modifications.Methods: In this research, the albumin was purified from human serum using chilled ethanol, followed by chromatographic methods. The purity of harvested albumin was evaluated by cellulose acetate membrane electrophoresis (CAME) and sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE). Western blotting (WB) analysis and thermostability were used for functional and stability measurement assessment, respectively.Results: SDS-PAGE and CAME sh...
