FSL 1
Purity: ≥95%
Biological Activity
FSL 1 is a TLR2/6 agonist (also a putative TLR10 ligand). Activates NF-κB. Induces pro-inflammatory cytokines including IL-8, IL-1β, CCL20 and TNF-α in vitro. Synergizes with IFNγ to induce CXCL10 release from melanoma cells.Technical Data

We used this molecule to serve as a control to induce TLR2 signaling. The differentiated THP-1 macrophages were treated with FSL-1 for staphylococcus aureus lipoproteins for 4 h and the TNFa in culture supernatants was measured by ELISA.
