Target intelligence / Profile preview
Streptococcus pneumoniae type 12F capsular polysaccharide (CPS 12F)
- Target
- CPS 12F
- Molecular classification
- Polysaccharide, Capsular Polysaccharide, Antigen
01
Overview
The Streptococcus pneumoniae type 12F capsular polysaccharide is a serotype-specific, high-molecular-weight carbohydrate polymer that forms the outermost layer (capsule) of the bacterium S. pneumoniae serotype 12F. This capsule is a critical virulence factor, protecting the bacterium from host immune responses and serving as a target for vaccine-induced immunity.
