    摘要: The present invention discloses fusion proteins comprising transferrin, lactoferrin or melanotransferrin fused to glucagon-like peptide 1 (GLP-1). In one embodiment of the invention, the fusion protein displays increased serum half-life as compared to a GLP-1 peptide in an unfused state. The invention includes a pharmaceutical composition comprising the GLP-1 fusion protein of the invention and a carrier. The fusion protein of the invention can be administered to a subject for treatment of diseases or conditions treatable by GLP-1, including, but not limited to, diabetes, obesity, congestive heart failure and inflammatory bowel syndrome.

    摘要: Improved methods for direct purification of product immunoglobulins or their derivatives from large volumes of mammalian cell culture medium include directly subjecting the cell culture medium to cation exchange treatment, so as to adsorb the product but not the contaminants. The eluted product is then recycled, or is applied to anion exchange, for further purification, and optionally subjected to additional steps. The product may be obtained in a form suitable for clinical applications, if desired.
