Methods for Separation of Proteins | IOVS | ARVO Journals

Most of the methods available for general separation of proteins have been applied to the proteins of the crystalline lens. The classical work of Mörner, in 1894, suggested that there were three soluble lens proteins which he labeled α-, β- and γ-crystallin and an insoluble residue which he called albuminoid.
