title: Immunochemical relationship between alpha-amylases of rat liver, serum, pancreas and parotid gland.
abstract: 1. Rabbit antisera to purified rat parotid alpha-amylase were prepared. 2. The relationships between rat parotid-gland, pancreatic, serum and liver amylase were investigated by using the antisera in immunodiffusion, immunoelectrophoresis and immunoinhibition experiments. 3. Serum and liver amylase were identical, and very similar to parotid-gland amylase; pancreatic amylase was, however, quite distinct, and showed only some of the determinants present on parotid-gland amylase. 4. The data strengthen the suggestion that the liver is the main source of serum amylase.
