Abstract
The soluble bovine eye lens cytoplasm has been separated in its α-, β- and γ-crystallin fractions, using size exclusion chromatography. The individual α-crystallin fractions have been characterized using moving boundary and equilibrium sedimentation and photon correlation spectroscopy. The α-crystallin fractions represent a very broad distribution in molar mass from 500 000 to 1 100 000 g/mole, with a maximum at 650 000 g/mole. This population contains also a broad distribution of hydrodynamic structures, ranging from compact to more asymmetric structures; the main population has a frictional coefficient f/f 0 ratio of (1.45±0.05). These structural properties perfectly fit the micellar model.
