This lattice type is usually created when crystals are formed from micellar solutions using vapour diffusion methods or batch method [61] , [62] , see Fig. 4 …
WebOct 9, 2013 · A survey of membrane-protein crystal structures published since 2012 reveals that the direct crystallization of protein-detergent complexes remains the dominant methodology; in addition, lipidic ... WebProtein crystallization involves the adjustment of numerous parameters giving rise to a multitude of possible conditions. For membrane proteins, detergent has to be added, which increases the number of important parameters even more. 50 Each experiment under any given condition requires a certain mixture, the production of which is tedious.
WebJan 1, 2015 · By comparing detergent concentration to crystallization success, an optimal range of protein and detergent concentrations for crystallization was determined (Fig. 12 B). Based on this analysis, it was determined that crystallization requires a minimum protein concentration of 6.9 mg/mL and a maximum of 10.5 mg/mL.
