As structural biology continues to evolve, many laboratories are integrating cryo-electron microscopy (cryo-EM) alongside traditional X-ray crystallography to tackle large, flexible biomolecular complexes.
In a newly featured IUCr paper, "Breaking barriers: transitioning from X-ray crystallography to cryo-EM for structural studies," researchers provide a practical roadmap of the cryo-EM workflow using the epigenetic regulator ATAD2B as a model system. The authors openly share strategies for overcoming common sample preparation hurdles—including diagnosing heterogeneity, optimizing grid freezing conditions, and removing persistent contaminants such as GroEL.
Whether your lab is just beginning to adopt cryo-EM or looking to refine your vitrification and screening protocols, this paper offers valuable, actionable insights to help streamline your structural determination pipeline.
