Publication Abstract from PubMed 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. Radiation stability of proteinase K crystals grown by LB nanotemplate method.,Pechkova E, Tripathi S, Ravelli RB, McSweeney S, Nicolini C J Struct Biol. 2009 Dec;168(3):409-18. Epub 2009 Aug 15.
