X06DA-PXIII [1] at the Swiss Light Source, celebrating its 1,000 PDB entries, is among the most productive macromolecular crystallography beamlines worldwide. X06DA receives light from a 2.9 T superbend magnet, which provides beam performance comparable to undulators, but with very high stability. Therefore, X06DA is not only compatible with high-throughput measurements – well appreciated by 1/3 industrial usage – but is also highly optimized for experimental phasing experiments. Beyond its remarkably fast and stable optics, X06DA offers unique hardware [2] and software tools for advanced phasing data collection protocols [3], which improve both the quality of the anomalous signal and the efficiency with which it is being measured. The current increase in number of structures solved by native SAD (single-wavelength anomalous dispersion) reflects the routine use of a simple and fast data collection protocol developed at X06DA [4], which has proven effective on highly challenging cases [5]. In situ X-ray diffraction screening of crystallization plates, available during users beamtime with a fast switching (two minutes) between in situ and cryogenic mode, further expands the capabilities of the beamline and is available as a service from the integrated crystallization facility [6].

Organized Storage and Transport of Cryo-EM Grid Boxes

Simply and Securely Know Where Each Grid Box Is

Simplify how you store and transport your cryogenically cooled Cryo-EM specimen grids. Each puck holds up to 24 round Cryo Grid Boxes (96 grids). A custom serial number on each puck allow easy sample tracking. An 8 puck capacity storage cane is compatible with standard refrigerators, such as the HC34. The compatible shelved shipping cane holds 7 pucks and can be used with a CX100 dryshipper.

Eliminate Transferring Crystals from Cryovials to Uni-Pucks

Many labs are filled with both cryovials and Universal Pucks (Uni-Pucks). When cryocooling your crystals, it may be hard to predict which storage system will be required once your beam-time rolls around. The CombiPuck was designed so that you don’t have to know. The CombiPuck accepts samples cryocooled into SPINE standard cryovials in a form factor compatible with Uni-Puck handling robots.

Come Cryocool Your Crystals, Simplify Cryoprotection and Eliminate Ice

(Users from the McKenna Lab, University of Florida, Prepare Samples for Plunge Cooling Tests at MiTeGen’s NAF)

The NANUQ™ Access Facility (NAF) is located at MiTeGen’s headquarters in Ithaca, NY, USA, just a few miles away from the CHESS synchrotron beamlines. The facility and support services enable crystallographers to access state-of-the-art equipment that will optimize the cryocooling of their crystals, while reducing or eliminating the need for cryoprotectants. The laboratory facility includes a NANUQ™ cryocooling device, liquid nitrogen supplies and accessories, a Carl Zeiss Discovery V8 stereo microscope outfitted for crystallography, and all the required tools and accessories for controlled, reproducible cryocooling into the Universal V1 Pucks (Uni-pucks). MiTeGen personnel are on site to directly assist in ensuring the success of NAF users.
