[edit] Carbohydrate Name

Phosphorylcholine (PC)

[edit] Carbohydrate Class

Miscellaneous

[edit] Source Microbe

Streptococcus pneumoniae

[edit] Basic Structure

N/A

[edit] Proposed functions

Antibodies directed against phosphorylcholine (PC), a major epitope on the cell wall polysaccharide, protect against pneumococcal infections in mice; the role of anti-PC antibodies in humans, however, remains controversial

[edit] Antigenic Nature used to produce antibodies

ASRNKANDYTTEYSASVKGRFIVS [peptide1]

[edit] Carrier Name

BSA

[edit] Conjugation Method

BSA (5 mg) was dissolved in a 0.1 M sodium citrate solution (pH 5.5; 500 ml) to provide a BSA:peptide ratio of 1:25. Glutaraldehyde (0.1%) was added, and the solution was incubated for 1 h at room temperature. The reaction mixture was dialyzed against phosphate-buffered saline (PBS) for 5 days at 4C

[edit] Antibodies

Antisera

[edit] Antibody type and class

N/A

[edit] Assay System

ELISA, Opsonization and protection assays

[edit] Cross-reactivity

N/A

[edit] Proposed epitopes

N/A

[edit] Proposed Utility

This peptide was able to inhibit the binding of anti-PC monoclonal antibodies to PC-BSA
