Description: The eBioLD5 monoclonal antibody reacts with mouse Toll-like receptor 1 (TLR1, CD281). TLR1 is an approximately 98 kDa protein belonging to the Toll-like receptor family, and is closely-related to mouse TLR6 in both structure and function. Through the formation of a complex with TLR2, TLR1 is able to bind bacterially-derived triacyl lipopeptides, as well as soluble factors released from Neisseria meningitidis. TLR1 is expressed by macrophages and macrophages in TLR1-deficient mice display impaired production of inflammatory cytokines upon stimulation with triacyl lipopeptides and lipoproteins from mycobacteria.
