    摘要: Provided herein are crystalline forms of a human IgG Fc variant comprising triple-mutation M252Y/S254T/T256E that provides for increased binding affinity to human neonatal Fc receptor, methods of obtaining such crystals and high-resolution X-ray diffraction structures and atomic structure coordinates. Also provided are machine readable media embedded with the three-dimensional atomic structure coordinates of the human IgG Fc variant and methods of using them.
