Abstract
The present invention provides a method for preparing high-purity recombinant human serum albumin and its applications as a drug and biopharmaceutical excipient. The recombinant human serum albumin from Oryza sativa (OsrHSA) prepared by the present invention can be replaced of plasma-derived human serum albumin for uses of the clinic and pharmaceutical excipients in term of safe and effective. Furthermore, it can effectively maintain the biological activity of biological macromolecules.
