Cell wall preparation of S. cerevisiae

Zymosan, an insoluble preparation of cell wall from Saccharomyces cerevisiae, activates macrophages via TLR2. TLR2 cooperates with TLR6 and CD14 in response to zymosan [1]. Zymosan is also recognized by Dectin-1, a phagocytic receptor expressed on macrophages and dendritic cells, which collaborates with TLR2 and TLR6 enhancing the immune responses triggered by the recognition of Zymosan by each receptor [2].


Specificity: TLR2 and Dectin-1 agonist

Working concentration: 1 - 10 μg/ml

CAS number: 58856-93-2

Endotoxin level: EndoFit™ (<0.001 EU/μg)

Solubility: Insoluble (resuspended zymosan results in a cloudy suspension)


• 100 mg Zymosan
• 10 ml sterile endotoxin-free water

Zymosan is shipped at room temperature and should be stored at 4°C. Resuspended zymosan may be stored at 4°C for at least 6 months.
