Pam3-Cys-OH（Cat No.:I043234）, also known as palmitoyl-3-cysteine, is a synthetic lipopeptide that mimics the structure of bacterial cell wall components. It consists of a cysteine residue linked to a palmitoyl group, which provides a hydrophobic tail, and is commonly used in immunology research. Pam3-Cys-OH acts as a ligand for Toll-like receptor 2 (TLR2), triggering innate immune responses. This activation promotes the production of pro-inflammatory cytokines, making it a valuable tool for studying immune signaling pathways, host-pathogen interactions, and the development of vaccine adjuvants or immunotherapies.
