CarboDB Group B antigen 2409
From DrugPedia: A Wikipedia for Drug discovery
Carbohydrate Name
Group B antigen
Carbohydrate Class
Capsular polysaccharide
Source Microbe
Streptococcus Group B strain M732
Basic Structure
This polysaccharide had a molecular size > 5 x 106. Its main chemical constituents were sialic acid (24%), galactose (25%), a sugar tentatively identified as heptose (21%), glucose (13%), glucosamine (10%) and mannose (7%)

Antibody type and class
N/A
Assay System
Capillary precipitin tests, immunodiffusion tests, immunoelectrophoresis
Cross-reactivity
This antisera cross-reacted with the TCA antigenas well as the EDTA-non pH titrated antigen and the group B antigen extracted with formamide from strain 090R or D136C
Proposed epitopes
L-rhamnose was the immunodominant sugar for the formamide-extracted B antigen
Proposed Utility
This antisera has helped determine that two antigens that react identically with each other and with similar specificities of antibody, yet with different immunodominant determinants
