1. 1. We examined the major surfactant-associated proteins in a number of species by using two-dimensional gel electrophoresis, protein blotting and immunostaining. 2. 2. All species have a 30,000 to 35,000 mol. wt protein group consisting of multiple isoforms with isoelectric points ranging from pH 4.4 to 5.6. 3. 3. The techniques used in this study have resolved three component subgroups within the 35 K group. 4. 4. A group of proteins at 60,000-65,000 mol. wt has also been consistently identified. 5. 5. We conclude that remarkable similarity exists among the major surfactant-associated proteins from various mammals with regard to isoelectric points, molecular weights and antigenic sites.
