The rocking curve of protein crystals contains a lot of useful information concerning crystal quality, most of which is lost owing to the superimposition of spurious features appearing in these fragile materials after growth, during handling and mounting. To minimize such data spoiling, an experimental setup to perform in situ X-ray diffraction experiments during crystal growth has been designed. The setup, which includes video observation to allow the correlation of crystal shape, size and growth rate with X-ray data, has been used to assess the mosaicity of tetragonal lysozyme crystals during crystal growth. The full width at half maximum (FWHM) of diffraction peaks collected from these crystals changes during the growth process as a (directly proportional) response to the growth rates and the different development of different domain blocks. These changes in the domain distribution and FWHM with time involve a 'zonation' of the crystals, which show very different rocking curves in different parts of their volume. The rocking curves recorded in situ from growing crystals are easier to understand than those from crystals that have suffered even minor handling.
