Development and Potential Applicaton of Monoclonal Antibodies Against F18 pili of Escherichia coli from Swine with Postweaning Diarrhea and Edema Disease
Abstract: Fl8ab pili of the reference Escberichia coli(E.coli) strain 107/86 from swine with edema disease were purified by a modified procedure. After thermo-separating from the bacterial cells, the pili were concentrated by precipitation with arnmoniurn sulfate, dialyzed, and solubilized in buffer containing deoxycholate. The fraction containing the pili was purified further by ultra-centrifugation in a sucrose gradient. After ultra-centrifugation, the purified pili from strain 107...
