title: [Determination of the IgA 7 S/IgA 11 S ratio in human bronchial secretion by thin layer gel filtration immunoelectrophoresis (author's transl)].
abstract: After extraction by treatment with Ecteola-cellulose, IgA 11 S and IgA 7 S from human bronchial secretion were first separated by thin-layer gel filtration in Ultrogel AcA 3-4, and then were analyzed by crossed immunoelectrophoresis with an immune serum against alpha chain. Precipitation areas were measured separately. A correlation factor was necessary to express IgA 7 S in terms of IgA 11 S: it was calculated with standard curves made with serum and colostral IgA.
