Abstract

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