Product News: 50th Rigaku ACTOR™ robotic protein crystal handling system purchased by the Medical Research Council

08 May 2008


Rigaku Americas Corporation is pleased to announce the sale of the 50th Rigaku ACTOR robotic protein crystal handling system to the Medical Research Council (MRC) Laboratory of Molecular Biology in Cambridge, UK.

The system was chosen by the MRC as an upgrade for their in-house X-ray diffraction facilities and in support of crystallographic studies carried out in the laboratory, which seek to understand the structure, function and interactions of biologically important molecules at the atomic, molecular and supra-molecular level. A significant milestone for Rigaku, sale of the 50th ACTOR will be marked by a special commemorative plaque affixed to the exterior of the instrument. Dr. Andrew Leslie, Group Leader for structural studies of macromolecular complexes within the Division of Structural Studies, commented, "I'm personally delighted that we are getting the 50th system, congratulations to all concerned!"

As the world's first commercial robotic system for automated crystal sample mounting and storage, ACTOR eliminates much of the physical handling of samples by crystallographers required during routine screening and data collection either in the lab or at the beamline. It is an automated system designed to store frozen protein crystals, mount them sequentially, align them to the X-ray beam, collect complete data sets, and return the crystals to storage.

The ACTOR automated crystal mounting and data collection technology was co-developed by Rigaku with Oceaneering Space Systems (OSS), a division of Oceaneering International, Inc., under a license from Abbott® Laboratories for the purpose of offering a commercial high-throughput crystallography automation system. Astex™ Therapeutics Ltd. (Cambridge, UK) purchased the first ACTOR system in 20011. In 2002, the Rigaku ACTOR was honored with an R&D 100 Award for technical innovation. In 2005, Rigaku introduced a version of robot for small molecule chemical crystallography called the ACTOR SM.
