An inexpensive automatically operated device for the flash annealing of crystals of macromolecules

A small, inexpensive and automatically operated device for the flash annealing of crystals of macromolecules is presented. Operation of the device is completely integrated within the ESRF beamline control graphical user interface for macromolecular crystallography experiments, mxCuBE, and the device can thus be controlled either from the beamline control cabin or by users accessing the beamline remotely.

Online collection and analysis of X-ray fluorescence spectra on the macromolecular crystallography beamlines of the ESRF

This paper describes the implementation of an online tool for the collection and qualitative analysis of X-ray fluorescence spectra that allows the identification of ions in a crystal or a solution of a biological macromolecule.
