| PolysacDB ID | 2348 |
| Carbohydrate Name | K antigens [Capsular polysaccharide] (Drugpedia) |
| Carbohydrate Class | Capsular polysaccharide |
| Microbe Name | Sinorhizobium meliloti strain NRG34 (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 Function | 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 | Whole cells |
| Carrier Name | Nil |
| Conjugate Method | Nil |
| Antibodies | Mab 7 |
| Antibody Type Class | IgGM |
| Assay System | ELISA and immunoblotting |
| Cross Reactivity | This Mab was specific to S. melliloti |
| Proposed Epitope | 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 |
| Curator ID | AA + AS |
| Date of Curation | 10-04-2011 |

| Carbohydrate Name | K antigens [Capsular polysaccharide] (Drugpedia) |
| Carbohydrate Class | Capsular polysaccharide |
| Microbe Name | Sinorhizobium meliloti strain NRG185 (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.

| Conjugate Method | Nil |
| Antibodies | Mab 8 |
| Antibody Type Class | IgGM |
| Assay System | ELISA and immunoblotting |
| Cross Reactivity | This Mab was specific to S. melliloti. But MAb 8 recognized the K antigens from both the homologous strain, S. meliloti NRG185, and S. meliloti NRG286 |
| Proposed Epitope | 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 |
