Self-interaction chromatography as a tool for optimizing conditions for membrane protein crystallization [PDF]

, 2009
The second virial coefficient, or B value, is a measurement of how well a protein interacts with itself in solution. These interactions can lead to protein crystallization or precipitation, depending on their strength, with a narrow range of B values ...
