Towards a Human Crystallin Map

This paper describes a first approach to establish a master data base of human lens crystallins obtained by computer analysis of standardized two-dimensional lenticular protein patterns. To facilitate the eventual identification of the spots, the major crystallins have been separated into alpha-, beta H-, beta L- and gamma-crystallin fractions by gel filtration. The authors encourage colleague investigators to collaborate in a common effort in order to arrive eventually at a two-dimensional gel data base of all lenticular proteins.
