Pharmaceutical Companies Participation in
High-Quality Protein Crystal Growth Experiment on Kibo

March 20, 2014 (JST)

Japan Aerospace Exploration Agency (JAXA)

The Japan Aerospace Exploration Agency will begin the first experiment of the second series for the High-Quality Protein Crystal Growth Experiment (PCG)*1 using the environment on the Japanese Experiment Module "Kibo" of the International Space Station (ISS). Chugai Pharmaceutical Co., Ltd. and Interprotein Corporation will participate in the experiment.
Other than those companies, 18 academic organizations including universities will also join the experiment (as shown in List 1 below).
One of our objectives of the second series of the JAXA PCG is to contribute to enhancing Japan's industrial competitiveness by leveraging our world-class high quality PCG technology and knowhow in space that has been fostered. For fulfilling that objective, we established a new system*2 to facilitate application of our technology and knowhow by private companies such as an introduction of a trial-use system.

We are confident that JAXA PCG will contribute to the progress of research and development for medicine, industrial enzyme, and other areas by acquiring precise 3D protein structure data, which is the JAXA PCG target, and understanding the function of protein based on the precise structure data. We will conduct six experiments in space in total by regularly performing an experiment once every six months.

Note 1: Outline of the first experiment of the second series for the High-Quality Protein Crystal Growth Experiment (PCG)
The first series was performed between 2009 and 2013 with six space experiments. The second one consists of six space experiments again from 2014.
The first experiment for the second series will be as follows.
Launch date: March 26, 2014
Launch site: Baikonur Cosmodrome in Kazakhstan
Scheduled return date: May 14, 2014
Landing location: Kazakhstan
Return flight: By Soyuz Spacecraft

The first experiment of the second series will be supported by Astronaut Koichi Wakata, who now resides at the ISS.

Note 2: Private company participation system
In addition to our conventional way of providing experiment opportunities to private companies, we offer a package of our space experiment preparation knowhow* and a chance to conduct a world-class leading-edge space experiment.
Also, by utilizing our trial-use system, which has been newly set up, a private company can actually verify and determine the effectiveness of using the Kibo prior to paying.

(*) The knowhow includes verification technology of protein quality, removal technology of impurities in protein liquid, and how to find conditions to grow high-quality protein crystallization in space.
