TLR1

SKU: orb1308750

Description

TLR1 is a cell-permeable synthetic peptide that mimics the TIR domain/BB-loop, functioning as a potent inhibitor of IL-1 receptor signaling. This tool compound is widely used in vitro and in vivo to study inflammatory pathways, NLRP3 inflammasome activation, and interleukin-mediated immune responses.
