[edit] Carbohydrate Name

O-polysaccharide

[edit] Carbohydrate Class

O-polysaccharide [LPS]

[edit] Source Microbe

Pseudomonas syringae IMV 7836 pv. Atrofaciens

[edit] 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-]

[edit] Antibodies

Mab Ps1a'

[edit] Antibody type and class

IgG3

[edit] Assay System

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

[edit] Cross-reactivity

"Mab Ps1a' cross-reacted with all strains from subgroups 1b, 1c, and 1x but not with strains from 1d."

[edit] Proposed epitopes

The epitope of Mab1a' is related to the D-Rha(alpha1-3)D-Rha(alpha1-2)D-Rha site of the O-polysaccharide backbone consisting of tetra-D-rhamnose repeats. The residue (alpha1-3)DRha( alpha1-2) is immunodominant for epitope of Mab 1a'

[edit] Proposed Utility

This Mab was useful for elucidation of the LPs structure
