Carbohydrate Name

Lipopolysaccharide

Carbohydrate Class

Lipopolysaccharide

Source Microbe

Bacteroides fragilis

Basic Structure

The polysaccharide part of the LPS mainly consists of two fractions : PSI : β-D-Galp(1-->6)β-D-Galp(1-->6)β-D-Galp(1-->6)Residue1-α-D-Glcp [branched to Residue no. 2](1-->2)α-L-Rhap and PSII : β-D-Galp(1-->4)α-D-Glcp [Branched to β-D-Galp(1-->6)](1-->2)α-L-Rhap

Proposed functions

LPS polysaccharide of B. gingivalis may represent a virulence factor

Antigenic Nature used to produce antibodies

Outer membrane extract of B. fragilis 23475

Carrier Name

nil

Conjugation Method

nil

Antibodies

Mab BF6

Antibody type and class

N/A

Assay System

Enzyme Immunoassay, Inhibition assay, Immunoblotting

Cross-reactivity

This antibody cross-reacted with 66 strains of B. fragilis, 2 strains of B.thetaiotaomicron, 2 strains of B. ovatus. Also partially cross-reacted with one B. ureolyticus strain.

Proposed epitopes

N/A

Proposed Utility

Using this Mab LPS can be easily detected in bacterial antigen preparations and clinical samples.
