Antigenic Nature used to produce antibodies | Formalin-killed whole cell vaccines |
Carrier Name | Nil |
Conjugation Method | Nil |
Antibodies | Antisera |
Antibody type and class | N/A |
Assay System | Capillary precipitin tests, immunodiffusion tests, immunoelectrophoresis |
Cross-reactivity | This antisera cross-reacted with the TCA antigenas well as the EDTA-non pH titrated antigen and the group B antigen extracted with formamide from strain 090R or D136C |
Proposed epitopes | L-rhamnose was the immunodominant sugar for the formamide-extracted B antigen |
IEDB Epitope | N/A |
Proposed Utility | This antisera has helped determine that two antigens that react identically with each other and with similar specificities of antibody, yet with different immunodominant determinants |
