Random Microseeding: A Theoretical and Practical Exploration of Seed Stability and Seeding Techniques for Successful Protein CrystallizationClick to copy article linkArticle link copied!
Abstract
Microseed matrix-screening combined with random screens (rMMS) is a significant recent breakthrough in protein crystallization. In this study, a very reproducible assay for crystal seeds was set up that allowed the following recommendations to be made: (1) the suitability of a solution for suspending seed crystals can be predicted by incubating (uncrushed) crystals in it for one day and observing crystal stability. (2) For routine rMMS, seed crystals should be suspended in the crystallization cocktail that gave the original crystals. (3) Seed crystals can be suspended in PEG or NaCl solutions to reduce the prevalence of salt crystals. (4) Protein complexes can be seeded with seed crystals suspended in PEG. If necessary, seed crystals can also be suspended in the original crystallization cocktail with any individual ingredients that destabilize the complex removed. (5) “Preseeding” of the protein stock should not be used if rMMS is available, because it is less effective. (6) Seed crystals can be harvested from microfluidic devices. (7) Heterogeneous nucleants and cross-seeding are less effective than rMMS, but they can be used if seed crystals cannot be obtained. A theoretical case and practical suggestions are also put forward for producing crystals with different space groups.
