Carbohydrate Name

Lipopolysaccharide

Carbohydrate Class

Lipopolysaccharide

Source Microbe

Shigella flexneri serotype 2b

Basic Structure

Chemically, the O-antigen is a polysaccharide chain of variable length, built up by repetitive sequences of tetra- to hexasaccharides. It consists of a basic tetrasaccharide repeating unit consisting of three rhamnoses and one N-acetylglucosamine was common to all S. flexneri strains (except serotype 17): -2)-α-L-Rhap-(1-->2)-α-L-Rhap-(1-->3)-α-L-Rhap-(1-->3)-β-D-GlcpNAc-(1-->


Proposed functions

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

Antigenic Nature used to produce antibodies

Heat killed cells

Carrier Name

nil

Conjugation Method

nil

Antibodies

Mab MASF(7,8)-l

Antibody type and class

IgG3

Assay System

ELISA, agglutination tests

Cross-reactivity

This Mab showed excellent specificity for the 7,8 antigenic determinant [S. flexneri serotypes 2b, 3a, 5b, and X]

Proposed epitopes

This Mab apparently interact with the α-D-glucose p(1-->4)-α-L-rhamnosyl pIII epitope

Proposed Utility

This Mab can be used for detection and identification of shigella flexneri species
