Carbohydrate Name

Smooth Lipopolysaccharide

Carbohydrate Class

Lipopolysaccharide

Source Microbe

Rough Brucella melitensis strain B115

Basic Structure

The S-LPS of smooth-type Brucella spp. contains two distinct antigenic determinants designated A and M

Proposed functions

LPS is most unusual constituents of outer membrane. It plays important role in host defence avoidance. LPS contributes to the negative charge of the bacterial surface. Lipid A is often toxic and act as endotoxin

Antigenic Nature used to produce antibodies

Whole cells

Carrier Name

nil

Conjugation Method

nil

Antibodies

Mab 03E05

Antibody type and class

IgG3

Assay System

ELISA and immunoblotting

Cross-reactivity

This antibody was highly specific for S-LPS of the M dominant strain (M). This Mab cross-reacted with O-PS of B. abortus 99 but did not bind to R-LPS of B. melitensis B11; also did not cross-react with Y. enterocolitica0:9 LPS

Proposed epitopes

α1-->3 linkages seem to be an important part of the epitope

Proposed Utility

this mAb may be particularly useful for typingsmooth Brucella strains
