[edit] Carbohydrate Name

Lipopolysaccharide

[edit] Carbohydrate Class

Lipopolysaccharide

[edit] Source Microbe

Shigella flexneri serotype X

[edit] Basic Structure

LPS is a complex macromolecule composed of the biologically active lipid A moiety, covalently attached core oligosaccharide, and distally linked polysaccharide O-side chain. The O-antigen part consists of the following residues : -3)-α-D-GlcpNAc-(1-->3)-β-L-Rhap [branched to α-D-Glcp-(1-->2)] -(1-->2)-α-L-Rhap-(1-->2)-β-L-Rhap-(1-

[edit] Proposed functions

LPS plays an important virulence role based on its antiphagocytic and endotoxic properties

[edit] Antigenic Nature used to produce antibodies

Phenol killed cells

[edit] Carrier Name

nil

[edit] Conjugation Method

nil

[edit] Antibodies

Mab X-1

[edit] Antibody type and class

IgG2a

[edit] Assay System

ELISA, immunodiffusion

[edit] Cross-reactivity

This Mab cross-reacted with 3a and 5b LPS

[edit] Proposed epitopes

This Mab reacted with alkali-treated LPS

[edit] Proposed Utility

This Mab can be used for antigenic characterization of Shigella LPS
