  • PubMed Abstract: 

    A detailed analysis of structural and intensity changes induced by X-ray radiation is presented for two types of proteinase K crystals: crystal grown by classical hanging drop method and those grown by Langmuir-Blodgett (LB) nanotemplate. The comparison of various parameters (e.g. intensity per sigma ratio, unit-cell volume, number of unique reflections, B-factors) and electron density maps as a function of radiation dose, demonstrates that crystals, grown by the LB nanotemplate method, appear to be more resistant against radiation damage than crystals grown by the classical hanging drop method.
