| PolysacDB ID | 2563 |
| Carbohydrate Name | Exopolysaccharide xanthan (Drugpedia) |
| Carbohydrate Class | Capsular polysaccharide |
| Microbe | Xanthomonas campestris pv. campestris 649 (NCBI Taxonomy) (Drugpedia) |
| Basic Structure | It consists of a β1-->4 glucose polymer, i.e. a cellulose backbone, with β1-->3 substituted trisaccharide side-chains of (mannose-β1-->4 glucuronic acid-α-1-->2-mannose-β-1-->3)- on alternate glucose residues. The side-chain is variably acylated. The inner mannose may have an O-6 acetyl group and the terminal mannose a 4,6- bound pyruvate ketal

| BCSDB Structure | N/A |
| Proposed functions | The exopolysaccharide xanthan from Xanthomonas campestris is an interesting carbohydrate polymer, with striking rheological properties which make it useful as a food additive (gelling agent) and also as a potential vehicle in enhanced oil recovery |
| Antigenic Nature used to produce antibodies | Xanthan |
| Carrier Name | Nil |
| Conjugation Method | Nil |
| Antibodies | Mab D3 |
| Antibody type and class | IgG2a |
| Assay System | ELISA |
| Cross-reactivity | This Mab was specific to Xanthan and did not cross-react with Cellulose |
| Proposed epitopes | The specificity was mainly against the side-chain of xanthan. This Mab was assumed to be directed against the nonsubstituted trisaccharide with the inner mannose-glucuronic acid being immunodominant |
| IEDB Epitope | N/A |
| Proposed Utility | This Mab could be useful for structural studies, for detection purposes in commercial and agricultural settings, and for serological typing purposes |
