title: Familial temperature sensitive alpha 1 protease inhibitor (M1Anaheim).
abstract: An alpha 1 protease inhibitor which is sensitive to increased temperatures and which migrates in the same position as the normal M1 phenotype, has been identified. The sensitivity of the trypsin inhibitory capacity is an inherited characteristic, which is enhanced by acid conditions, as well as conditions during isoelectric focusing. Loss of the serum trypsin inhibitory capacity is not parallel to that of the serum elastase capacity, suggesting that the inhibitory sites for these proteases are oriented differently within the alpha 1 protease inhibitor molecule.
