... could be sedimented in a sucrose density gradient from a fresh cytosol or its crude fraction precipitated at 20-30% saturation of AmS, showing the sedimentation coefficient 3S. When analyzed by SDS-polyacrylamide gel electrophoresis (PAGE), all the proteins in partially purified CSF-1 samples entered...

.... The development of the ‘lentoid body’ is a multiphase process involving cell replication, synthesis of mucosubstances and a basement collagen membrane, cell aggregation and differentiation. Stage-specific synthesis of lens proteins confirms that the genes regulating normal differentiation in vivo are operating...
