The inhibitor to oyster ciliary activity was isolated from serum of cystic fibrosis patients and heterozygotes. The inhibiting protein fraction was a cation as judged by electrophoresis; it had a molecular weight of 125,000 to 200,000 as judged by gel filtration; and on diethylaminoethyl-cellulose chromatography it eluted with the immunoglobulin G fraction. The analogous fraction in normal individuals did not inhibit oyster ciliary activity.
