CSP-2, Competence-Stimulating Peptide-2

CSP-2 is a competence-stimulating signaling peptide from Streptococcus pneumoniae. Sequence-specific CSP variants activate cognate quorum-sensing pathways and are used to investigate bacterial competence and cell-cell communication.

• antimicrobial and host-defense research
• innate-immunity studies
• bacterial signaling or quorum sensing
• peptide-membrane structure-function analysis

Disulfide state, exact sequence, species origin and terminal chemistry define product identity. Use sequence-matched controls and consistent ionic conditions in antimicrobial or quorum-sensing assays.
