Recovery of proteins from dried polyacrylamide gels after fluorography. 
Several methods are available for recovering proteins electrophoretically from polyacrylamide gels directly after electrophoresis or after staining for protein (see, for example, Chapter 19 ).  Fluorography (see Chapter 17 ) is used to detect small amounts of proteins or specifically modified forms of proteins by labeling these with specific precursors such as (3)H-lysine or (3)H-acetate.
