WebCrystallization Kits The Sample Preparation and Crystal Screening Laboratory utilizes commercial kits from Molecular Dimensions, and Hampton Research. For a reasonable chance of crystallizing a sample, screen 4-5 trays. For cytosolic protein we recommend, JCSG+, PACT, SS12, PEG, and WIZARD. WebApr 4, 2006 · Temperature changes when complexing the protein and ligand. Often we complex our protein with the ligand of interest and incubate at 277 K for 30 min to 1 h before setting up the crystallization screens. If the ligand is rather insoluble, changing the temperature of this incubation may facilitate complex formation.
