Western blot analysis. Purified proteins were separated via 12% sodium dodecyl sulfate-polyacrylamide gel electrophoresis, transferred to nitrocellulose membranes, and then probed with known positive and negative goat sera. a Lane M, protein molecular weight marker; Lane 1, strong reactivity with known positive serum; b Lane M, protein molecular weight marker; Lane 1, result for negative serum
