Observations of systematic variation in the shapes of protein crystals have unique potential to report chemical effects on protein-protein interactions, because
An orthorhombic crystal form of subtilisin BPN' variant s88 exhibits a systematic variation in growth rates of its three unique faces, resulting in pronounced
A significant modification of an existing experimental technique based on the second-harmonic magneto-optical Kerr effect (SH-MOKE) is introduced. With a p
