Crystallogenesis of adenosine A(2A) receptor-T4 lysozyme fusion protein: a practical route for the structure.

abstract：:Rarely is any solution simply solute and water. In vivo, solutes, such as proteins and nucleic acids, swim in a sea of water, salts, ions, small molecules, and lipids, not to mention other macromolecules. In vitro, virtually all solutions contain a mixture of aqueous solvents, or "cosolvents" [i.e., solvent(s) in addi...
