[edit] Carbohydrate Name

Smooth Lipopolysaccharide

[edit] Carbohydrate Class

Lipopolysaccharide

[edit] Source Microbe

Rough Brucella melitensis strain B115

[edit] Basic Structure

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

[edit] 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

[edit] Antigenic Nature used to produce antibodies

Whole cells

[edit] Carrier Name

nil

[edit] Conjugation Method

nil

[edit] Antibodies

Mab 07F09

[edit] Antibody type and class

IgG1

[edit] Assay System

ELISA and immunoblotting

[edit] Cross-reactivity

This antibody was specific to a common epitope on A and M polysaccharides. 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

[edit] Proposed epitopes

Both α1-->2 and α1-->3 linkages seem to be an important part of the epitope

[edit] Proposed Utility

this mAb may be particularly useful for typingsmooth Brucella strains
