Carbohydrate Name

Lipopolysaccharide

Carbohydrate Class

Lipopolysaccharide

Source Microbe

Neisseria gonorrhoeae strain 4505

Basic Structure

Gonococcal lipopolysaccharide (LPS) is a complex of at least three major antigenic determinants. The ceramide part consists of the following residues : β-D-GalpNAc-(1-->3)-β-D-Galp-(1-->4)-β-D-Glcp-(1-?)-CER-(?--/Ceramide/. The core oligosaccharide part consists of the following residues : α-D-GlcpNAc-(1-->2)-L-gro [branched to β-D-Galp-(1-->4)-β-D-Glcp-(1-->4)] -α-D-manHepp-(1-->3)-L-gro-α-D-manHepp-(1-->5)-Kdo. The other part consists of the following residues : β-D-GalpNAc-(1-->3)-β-D-Galp-(1-->4)-β-D-GlcpNAc-(1-->3)-β-D-Galp-(1-->4)-β-D-Glcp-(1-->4)-L-gro [branched to α-D-GlcpNAc-(1-->2)-L-gro-α-D-manHepp-(1-->3)] -α-D-manHepp-(1-->5)-Kdo

Proposed functions

It is an important virulence factor

Antigenic Nature used to produce antibodies

heat-killed gonococcal strain 4505 cells

Carrier Name

nil

Conjugation Method

nil

Antibodies

Mab 3F11

Antibody type and class

IgG1

Assay System

ELISA

Cross-reactivity

This Mab cross-reacted with meningococcal LPS but failed to react with LPS isolated from Escherichia coli 0:111, the J-5 mutant of E. coli 0:111, or Salmonella minnesota R595

Proposed epitopes

D-galactosamine, α and β lactose residues seemed to be the part of the epitope

Proposed Utility

This Mab may be used for epitope elucidation of gonococcal LPS
