| 摘要 |
The present invention provides FGF-2 polypeptides that differ from the wild-type FGF-2 (SEQ ID NO:1) at least at amino acid position 56, 102 and 119, wherein the differences are Q56I, N102G, K119N substitutions, leading to FGF-2 polypeptides with higher thermostability, higher biological activity and higher resistance to proteolytic degradation. These polypeptides can be used in cell culture media. |
