Human TLR1 Neutralizing antibody - Polyclonal Rat IgG

PAb hTLR1 is a polyclonal antibody specific for human Toll-like receptor 1 (TLR1, CD281).

PAb hTLR1 was generated by DNA vaccination. Wistar rats received four hydrodynamic injections of pVAC-hTLR1, a plasmid expressing the extracellular region of human TLR1. The sera were harvested and the IgG fraction purified by Protein G affinity chromatography.

The control for use with PAb-hTLR1 is PAb Control.

TLR1 is predominantly expressed in the spleen and peripheral blood cells. No direct ligands have been identified so far for TLR1, and its function remains unclear. TLR1 seems to act as a coreceptor for TLR2. TLR1 and TLR2 form heterodimeric complexes on the cell surface and in the cytosol [1]. TLR1 and TLR2 were shown to cooperate in recognizing Borrelia burgdorferi outer-surface protein A lipoprotein OspA [2]. They also interact to recognize the 19-kD mycobacterial lipopeptide and several synthetic triacylated lipopeptides [3], but not diacylated lipopeptides. This suggests that TLR1 is able to discriminate among lipoproteins by recognizing the lipid configuration [4].
