[edit] Carbohydrate Name

Capsular polysaccharide

[edit] Carbohydrate Class

Capsular polysaccharide

[edit] Source Microbe

Cryptococcus neoformans Serotype A

[edit] Basic Structure

The capsular polysaccharide has a linear α-(1-->3)-linked mannose backbone that is substituted with nonreducing D-xylosyl and D-glucuronosyl acid groups. The mannose backbone is partially O-acetylated

[edit] Proposed functions

The capsular polysaccharide is an important virulence factor

[edit] Antigenic Nature used to produce antibodies

Glycoconjugates

[edit] Carrier Name

Sheep erythrocytes

[edit] Conjugation Method

The capsular polysaccharide was adsorbed with 0.1 ml of packed sheep erythrocytes for 2 hours at room temperature

[edit] Antibodies

Mab 471

[edit] Antibody type and class

N/A

[edit] Assay System

ELISA and Immunodiffusion

[edit] Cross-reactivity

This antibody cross-reacted with Serotype A,B,C and D serotypes

[edit] Proposed epitopes

N/A

[edit] Proposed Utility

used to differentiate various strains of all serotypes. This monoclonal antibody promoted opsonization of Cryptococcus cells
