There are three types of spin off technology which relate to the JAXA's protein crystallization projects in space, in these last 15 years. The first type is to obtain a patent on the crystallization device, 'gel-tube' and 'MicroChip', which has been designed for the space experiments but which can also be useful for the terrestrial crystallization in usual laboratory. The second type is to accumulate some know-how for the protein crystallization which is definitely useful for the terrestrial crystallization. The third one is to accumulate some know-how not for the crystallization but for the structure analysis, including sample preparation, diffraction data collection and the method for structure modeling, etc. As a result, it can be said that, to obtain more excellent results from space grown crystals, not only the crystallization process in space but also the whole technology for the protein structure analysis has been improved during JAXA's project. These technologies are contributed to the progress of the terrestrial protein crystallography and structure determination.
