In fava bean extracts the proteins were separated and characterized by gel filtration on Sephadex G 25 columns, cellogel electrophoresis and analytical ultracentrifugation.

Abstract
In fava bean extracts the proteins were separated and characterized by gel filtration on Sephadex G 25 columns, cellogel electrophoresis and analytical ultracentrifugation. The dried extract and its chromatographic fractions were used to detect serum antibodies to fava beans by passive hemagglutination tests. 75 patients affected by acute favism were studied by this method. Hemagglutination tests were positive in 5 patients (6.6%) at the onset of the hemolytic crisis but a rapid fall of the titres was observed in the subsequent days. β 1C/β 1A and immunoglobulin levels showed no significant changes. These results do not support the view that hypersensitivity to fava bean may be involved in the hemolysis of acute favism.File | Dimensione | Formato | |
