Specificity of monoclonal antibodies obtained by immunization of mice with trypsin-treated group a streptococcus culture
- 15 Downloads
Hybridomas producing monoclonal antibodies intensively reacting with group A streptococcus antigens in enzyme immunoassay were obtained as a result of immunizing mice with pepsin-treated cultures of group A streptococcus. All antibodies were referred to class M immunoglobulins. The reactions of monoclonal antibodies were completely inhibited by the pepsin-treated culture of group A streptococcus. The degree of inhibition with A-polysaccharide was lower, being 17.5 to 50.0 in different monoclonal antibodies. All the monoclonal antibodies obtained cross-reacted with antigens of murine and human epithelial tissues of the thymus and skin.
