| PolysacDB ID | 2350 |
| Carbohydrate Name | K antigens [Capsular polysaccharide] (Drugpedia) |
| Carbohydrate Class | Capsular polysaccharide |
| Microbe | Sinorhizobium meliloti strain NRG247 (NCBI Taxonomy) (Drugpedia) |
| Basic Structure | The K antigens of Sinorhizobium spp. are major strain-specific antigens, which commonly consist of small repeating units of a hexose and 1-carboxy-2-keto-3-deoxy sugars, such as sialic acid or 3-deoxy-D-manno-2-octulosonic acid (Kdo), although they vary in glycosyl residue composition, substitution patterns, linkage points, anomeric configuration, and size range. The K-antigens of rhizobia do not possess a lipid anchor
|
| BCSDB Structure | N/A |
| Proposed functions | K antigens may be involved in an early recognition step in S. meliloti-alfalfa interactions and that K antigen production is affected by plant-derived signals |
| Antigenic Nature used to produce antibodies | Whole cells |
| Carrier Name | Nil |
| Conjugation Method | Nil |
| Antibodies | Mab 9 |
| Antibody type and class | IgM |
| Assay System | ELISA and immunoblotting |
| Cross-reactivity | This Mab was specific to S. melliloti |
| Proposed epitopes | N/A |
| IEDB Epitope | N/A |
| Proposed Utility | The use of MAbs to study specific cell surface components from the bacteroids of Rhizobium leguminosarum have yielded interesting information about morphogenesis in the pea symbiont, including the temporal expression of specific epitopes during nodule development |
