Carbohydrate Name

O-polysaccharide [Terminal trisaccharide]

Carbohydrate Class

O-polysaccharide [LPS]

Source Microbe

Vibrio cholerae O1 LPS serotype Inaba

Basic Structure

The O-antigen part consists of (1-->2)-α-linked 4-amino-4,6-dideoxy-D-mannose (perosamine) whose amino group is acylated with 3-deoxy-L-glycero-tetronic acid. The terminal sugar in the Inaba O-antigen has a hydroxyl at the 2' position


Proposed functions

V. cholerae lipopolysaccharide (LPS), a critical component of the outer membrane that is required for virulence, is a known target for immune responses following infection or immunization. Antibodies specific for V. cholerae LPS are correlated with protection against cholera

Antigenic Nature used to produce antibodies

Glycoconjugates

Carrier Name

BSA

Conjugation Method

The purified carbohydrates were subjected to aminolysis to afford ethylenediamine derivatives, which were treated with squaric acid diethyl ester. The squaric acid monoesters, thus obtained, were treated with BSA to give neoglycoconjugates

Antibodies

Antsera

Antibody type and class

IgM and IgG2

Assay System

ELISA

Cross-reactivity

This antisera cross-reacted with V. cholerae Ogawa and Inaba LPS
