Carbohydrate Name

O-polysaccharide

Carbohydrate Class

O-polysaccharide [LPS]

Source Microbe

Pseudomonas syringae IMV 120a pv. Phaseolicola

Basic Structure

O-polysaccharides of the LPS consists of tetra- and tri-α-D-rhamnose repeats in the backbone [-3)D-Rha(α1->3)D-Rha(α1-->2)D-Rha(α1->2)D-Rha(α1] and [3)D-Rha(α1-->3)D-Rha(α1-->2)D-Rha(α1-]

Proposed functions

N/A

Antigenic Nature used to produce antibodies

Whole cells

Carrier Name

nil

Conjugation Method

nil

Antibodies

Mab Ps1d

Antibody type and class

IgM

Assay System

Agglutination, Ouchterlony immunodiffusion, ELISA, SDS-PAGE, and Western immunoblotting

Cross-reactivity

"This Mab reacted with P. syringae strains with pathovars atrofaciens, phaseolicola and 17 (80%) P. syringae strains for which the pathovar(s) has not been identified"

Proposed epitopes

The epitope was confined to lateral immunodominant substituents of (α1-->3)D-Rha, (β1-->4)D-GlcNAc, and (α1-->4)D-Fuc, respectively, which are all bound to the backbone-located D-rhamnose

Proposed Utility

This Mab strongly agglutinated homologous bacterial cells and precipitated soluble antigens
