Carbohydrate Name
O-polysaccharide
Carbohydrate Class
O-polysaccharide [LPS]
Source Microbe
Pseudomonas aeruginosa O5
Basic Structure
The LPS consists of three regions, namely O-polysaccharide, core oligosaccharide and lipid A. The core region of LPS is divided into the outer core and inner core. The inner core region consists of 2-keto-3-deoxyoctonic acid (KDO), heptose, phosphate, and probably ethanolamine. The outer core region commonly contains D-glucose, L-rhamnose, D-galactosamine, and L-alanine. The O-antigens consist of a trisaccharide repeating unit which consists of two uronic acid derivatives and one N-acetyl fucosamine residue
Proposed functions
N/A
Antigenic Nature used to produce antibodies
Formalin killed whole cells

Antibodies
Mab MF15-4
Antibody type and class
IgM
Assay System
ELISA, immunoblotting, ouchterlony immunodiffusion
Cross-reactivity
This Mab was specific to serotype O5
Proposed epitopes
The epitope consisted of N-acetyl fucosamine residues with an αglycosidic linkage and a minimum of six O repeats of serotype O5 polysaccharide
Proposed Utility
This Mab helps us shed some light on the nature of O-specific and common epitopes in the LPS of P. aeruginosa
