Human TLR2 Neutralizing antibody - Polyclonal Rat IgG

PAb hTLR2 is a polyclonal antibody specific for human Toll-like receptor 2 (TLR2, CD282).

PAb hTLR2 was generated by DNA vaccination. Wistar rats received four hydrodynamic injections of pVAC-hTLR2, a plasmid expressing the extracellular region of human TLR2. The sera were harvested and the IgG fraction purified by Protein G affinity chromatography.

The control for use with PAb-hTLR2 is PAb Control.

Toll-Like receptors (TLRs) play a critical role in early innate immunity toinvading pathogens by sensing microorganisms. These evolutionary conserved receptors recognize highly conserved structural motifs only expressed by microbial pathogens, called pathogen-associated microbial patterns (PAMPs). Stimulation of TLRs by PAMPs initiates a signaling cascade leading to the secretion of proinflammatory cytokines following NF-κB activation. To date ten human and twelve murine TLRs have been characterized, TLR1 to TLR10 in humans, and TLR1 to TLR9, TLR11, TLR12 and TLR13 in mice, the homolog of TLR10 being a pseudogene.

TLR2 is involved in the recognition of a wide array of microbial molecules. TLR2 recognizes lipoteichoic acid and lipoprotein from gram- positive bacteria, lipoarabinomannan from mycobacteria, and zymosan from yeast cell wall. Moreover, TLR2 participates in the recognition of some types of LPS. TLR2 is known to heterodimerize with other TLRs, a property believed to extend the range of microbial molecules that TLR2 can recognize. TLR2 cooperates with TLR6 in response to diacylated mycoplasmal lipopeptide [1], and associates with TLR1 to recognize triacylated lipopetides [2]. Furthermore, pathogen recognition by TLR2 is strongly enhanced by CD14 [3].
