Fluidigm TOPAZ(R) System Instrumental in Solving Asf1 Structure, Advancing Research in Cancer and Genetic Disease.
"The TOPAZ system allowed us to identify crystallization conditions we were not able to achieve through years of vapor diffusion trials and allowed us to go from a small amount of sample to having data in about a week," states Mair Churchill, Ph.D., Professor in the Department of Pharmacology at the University of Colorado at Denver and Health Sciences Center. "In addition, the scale-up from TOPAZ crystallization conditions to vapor diffusion was extremely efficient, requiring only 16 conditions to be set."
Researchers used TOPAZ screening chips to identify novel conditions using a small volume construct of the three-protein complex. The most promising conditions were scaled-up using vapor diffusion and standard TOPAZ translation protocols, resulting in 1.7 angstrom resolution of the protein crystal.
The TOPAZ system is unique in its usage of integrated fluidic circuits (IFCs) comprised of a network of channels and valves that enable crystallization study via the free interface diffusion technique. TOPAZ screening chips are capable of running up to 768 experiments in parallel with as little as 10 nanoliters of protein per condition.
Fluidigm Corporation develops and distributes systems based on the unique properties of IFCs to precisely control fluids on a nanovolume scale. The company's vision is to create and to lead a new industry in which IFCs bring unparalleled efficiencies to the life science and allied fields. Based in South San Francisco, California, the Company is privately held and backed by premier investors: Versant Ventures, Euclid SR Partners, InterWest Partners, Alloy Ventures, Lehman Brothers Healthcare Fund, the Singapore EDB, Bruce Burrows, Lilly BioVentures, the Invus Group, SightLine Partners, AllianceBernstein and GE Equity.
