Competence-Stimulating Peptide-2 (CSP-2)

Catalog No.: A48015
Quorum Sensing Signal Peptide
Competence-Stimulating Peptide-2 (CSP-2) is a 17-amino acid quorum sensing signal peptide that targets the ComD2 receptor in Streptococcus pneumoniae, exhibiting an EC50 of 50.7 nM. CSP-2 plays a critical role in regulating bacterial behaviors such as competence development, virulence, and biofilm formation. This peptide is essential for studying the mechanisms of bacterial communication and the associated phenotypic responses that impact pathogenicity.
