Toll-like receptor 4 (UniProt: O00206; also known as EC:3.2.2.6, hToll, CD284, TLR4) is encoded by the TLR4 gene (Gene ID: 7099) in human. Toll-like Receptors (TLRs) are transmembrane proteins that are expressed on various immune cells. They recognize specific molecular patterns associated with pathogenic species and provide an early defense mechanism against foreign organisms. They contain an N-terminal extracellular and a C-terminal cytoplasmic domain. The N-terminal region contains leucine-rich repeats (LRR) that recognize specific pathogen components. Although the ligand recognition mechanisms of the TLRs vary significantly, all TLR dimers exhibit similar overall arrangement. At least 13 different members of TLR family have been identified that detect different pathogen associated molecular patterns (PAMPs). TLR4 is a single-pass type I membrane glycoprotein that is highly expressed in heart, spleen, lung, muscle, and macrophages. It is synthesized with a signal peptide (aa 1-23), which is subsequently cleaved off to produce the mature form that contains an extracellular domain (aa 24-631), a transmembrane domain (aa 632-652), and a cytoplasmic domain (aa 653-89). TLR4 cooperates with LY96 and CD14 to mediate the innate immune response to bacterial lipopolysaccharide. It acts via MYD88, TIRAP and TRAF6, leading to NF-kB activation, cytokine secretion and the inflammatory response. In complex with TLR6, it also promotes sterile inflammation in monocytes/macrophages in response to oxidized low-density lipoprotein. It is also shown to be a crucial mediator in oxLDL-induced inflammatory cytokine expression and secretion in smooth muscle cells. TLR4 contains 18 LRR repeats and one TIR domain (aa 672-815) that mediates NAD+ hydrolase activity. D17 (Ref.: Yang, K., et al. (2014). PLoS ONE 9(4); e95935; Akashi, S., et al. (2000). J.

Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
