Comparison between purified alpha2-macroglobulin preparations from normal controls and patients with cystic fibrosis. Kinetic and structural properties of the complex with bovine trypsin.

cY,-?+lacroglobulin was purified from plasma obtained from three healthy controls and three patients with cystic fibrosis.The normal and patient preparations were indistinguishable antigenically and in their UV absorption spectra.Competitive inhibition by these preparations of the hydrolysis of benzoyl-L-arginine ethyl ester by bovine trypsin was
