The International Organization for Biological Crystallization (IOBCr) is a non-profit, scientific organization for scientists who study the crystallization of biological macromolecules and develop crystallographic methodologies for their study. It was founded in 2002 to create a permanent organ for the organization of the International Conferences for the crystallization of Biological Macromolecules (ICCBM).
The objective of the International Organization of Biological Crystallization is to promote research, innovation and practical applications in the field of biological crystallization. It organizes and supports interdisciplinary workshops and schools that foster professional contacts and mutual education between (bio-)crystallographers, (bio-)chemists, (bio-)physicists, and engineers. ICCBM conferences are organized biannually with venues that change regularly to maintain an international character. The objective of the IOBCr is the exchange of research results and encourage practical applications of biological crystallization. It organizes and supports interdisciplinary workshops. The attendance at the ICCBM meetings includes bio-crystallographers, biochemists, physicists, and engineers.
