Pancreatic Presecretory Proteins Larger
than Secretory Products
METHODS:
mRNA translation products  in reticulocyte
lysate (RL) or Wheat Germ (WG) compared
to pancreatic secretory products (SP)
derived from zymogen granules (ZG) or
homogenate (H) by SDS gel
electrophoresis.
RESULTS:
First demonstration that, below 60,000 kDa,
all primary translation products are larger
than secretory proteins by about 1500 kDa
