“…The range of electrophoretic literature has grown so large that the topics for reviews have tended toward extreme specialization: There are two brief reviews devoted to zone electrophoresis (105, 176) and one devoted to the problems in the electrophoretic separation of proteins (769); by contrast the special subject of immunoelectrophoresis has been reviewed extensively (59,65,505,605,659,939).
