  • Title: Chromatofocusing for separation of human cataractous lens low molecular weight proteins.
    Author: Kabasawa I, Watanabe M, Kimura M.
    Journal: Jpn J Ophthalmol; 1983; 27(4):592-7. PubMed ID: 6668752.
    Abstract:
    Four low molecular weight proteins (i.e. beta s, gamma H, gamma L1 & gamma L2 crystallins) were separated from the human cataractous lens cortex using gel filtration and chromatofocusing. Each of these four crystallins possessed its own subfractions in the pH gradient between 7.4 and 4.0 by chromatofocusing procedures. Analyses of the chromatofocusing patterns have further characterized the four crystallins. Polyacrylamide gel electrophoresis of these crystallin subfractions showed the possible separation of the heterogeneous protein bands.
