The Versatile Macromolecular Xtallography in-situ (VMXi) beamline is dedicated to room temperature data collection from macromolecular crystals (Xtals). It is an entirely automated facility for characterisation of, and data collection directly from, crystallisation experiments in situ.
There are several key advantages of in situ diffraction:
Currently VMXi offers:
which can help you with the following experiment types:
Under current conditions samples can be handled in the following ways:
If you would like to collect room temperature data at VMXi, please contact the beamline team letting us know the problem you are trying to solve, how samples will be provided and by when so we can review what we can support under the current COVID-19 operating conditions.
If you require further details, do not hesitate to get in touch.
