  • Title: Isotachophoresis and immunoelectrophoresis of water-soluble and -insoluble crystallins of the ageing bovine lens.
    Author: Bours J.
    Journal: Curr Eye Res; 1984 May; 3(5):691-7. PubMed ID: 6734250.
    Abstract:
    Water-soluble (WS) and water-insoluble (WI) crystallins were prepared from calf and bovine lenses. The WS-crystallins were analyzed by capillary isotachophoresis and by immunoelectrophoresis with polyvalent and alpha-, beta-, gamma-crystallin specific antisera. The WI-crystallins were first solubilized in formamide and then analyzed by the same methods. The WS-crystallins, which increase in weight, but decrease in % with increasing age, show an increase of alpha-crystallins from 36 to 43%, an increase of beta-crystallins from 42 to 48% and a decrease of gamma-crystallins from 22 to 9%. In the WI-crystallins, which increase in weight and in % with increasing age, the alpha-crystallins form the main portion with an increase from 54 to 61%. The beta-crystallins in WI remain fairly constant at about 37% and the gamma-crystallins decrease from 8 to 2%. Quantitatively, the alpha-crystallin is the major constituent of the lens. The alpha-crystallin and the beta-crystallin components are increasingly incorporated in WI with increasing age. The gamma-crystallin components are selectively incorporated into WI-protein. Immunologically, alpha-, beta- and gamma-crystallins were detected by the polyvalent and specific antisera in WS- and in WI- crystallins.
