μGISAXS and protein nanotemplate crystallization:: methods and instrumentation

Microbeam grazing- incidence small- angle X- ray scattering ( mu GISAXS) has been used and the technique has been improved in order to investigate protein nucleation and crystal growth, assisted by a protein nanotemplate. The aim is to understand the protein nanotemplate method in detail, as this method has been proved capable of accelerating and increasing crystal size and quality as well as inducing crystallization of proteins that are not crystallizable by classical methods. The nanotemplate experimental setup was used for drops containing growing lysozyme crystals at three different stages of growth.
