Pam3CSK4 VacciGrade™

Pam3CSK4 VacciGrade™ is a synthetic lipopeptide and a TLR2/1 ligand. It is prepared under strict aseptic conditions, is guaranteed sterile and is thoroughly tested to confirm the absence of endotoxins. Pam3CSK4 VacciGrade™ is suitable for preclinical studies.

For vaccination studies, activation through TLR2 is not generally recognized as a strong polarizing stimulus, as it generates variable Th responses that depend on the antigen(s) used and the site of injection.

Pam3CSK4 has been reported to efficiently increase antibody responses to influenza antigens [1] and to exert a strong local response. As an adjuvant, Pam3CSK4 has improved the efficacy of a DNA-based vaccine against Leishmania [2].

Pam3CSK4 VacciGrade™ is for research use only; it is not for use in humans.
