2D Gel Electrophoresis
Invention of this procedure enabled, for the first time, the following studies:
 Kinetics of movement of the entire cadre of secretory enzymes through
   sequential intracellular compartments during the biogenesis and secretion of
   pancreatic enzymes.
  Kinetic of release of all secretory enzymes from the acinar cell during
   conditions of rest and secretagogue stimulation.
  Folding of nascent pancreatic enzymes following their sequestration into the
   RER lumen.
  Kinetics of activation of pancreatic proteases leading to the autoactivation
   of pancreatic juice, a pathological process believed to play a role in the
   pathogenesis of acute and chronic pancreatitis in humans.
  Gene and protein expression studies of families of pancreatic enzymes as a
   function of changes in ratios of nutritional substrates in the diet and as a
   function of secretagogue stimulation.
