LYOPHILIZED COMPOSITION OF BONE MORPHOGENIC FACTOR HUMAN MP52 AND PROCESS FOR PREPARATION THE SAME

摘要

1. A lyophilized composition of bone morphogenetic factor human MP52, which comprises a mixture of bone morphogenetic factor human MP52 with mannitol at a mixing ratio in the range of 1:5 - 50 (ratio by weight). 2. The composition according to claim 1, wherein said bone morphogenetic factor human MP52 has been produced by genetic engineering technology. 3. A process for the preparation of a lyophilized composition of bone morphogenetic factor human MP52, which comprises adding mannitol to a purified solution of bone morphogenetic factor human MP52 in an amount to give a mixing ratio of bone morphogenetic factor human MP52 to mannitol in the range of 1:5 - 50 (ratio by weight) and then lyophilizing the resultant mixed solution. 4. The process according to claim 3, wherein said bone morphogenetic factor human MP52 has been produced by a genetic engineering technology.
