Carbohydrate Name
Exopolysaccharide xanthan
Carbohydrate Class
Miscellaneous
Source Microbe
Xanthomonas campestris pv. campestris 646
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
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 A6
Antibody type and class
IgM
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
Proposed Utility
This Mab could be useful for structural studies, for detection purposes in commercial and agricultural settings, and for serological typing purposes
