R848 (Resiquimod) is a potent dual agonist for TLR7 and TLR8, uniquely formulated for water solubility. This lyophilized compound excels in immunological research by activating immune cells, boosting the production of pro-inflammatory cytokines and type I interferons. Its rigorous quality control ensures no TLR2 or TLR4 contamination, distinguishing it from other products in the market. This makes it valuable for antiviral, antitumor research, and as a vaccine adjuvant.
