Background
TLR-3 is a single-pass type I receptor that binds to and signals the presence of microbial pathogens and double stranded RNA (dsRNA) viruses. Signaling through TLR-3 can promote the NF-?B pathway to initiate innate and adaptive immune responses to bacterial and viral infections, as well as the p53 pathway to trigger apoptosis in cells infected with dsRNA viruses. TLR-3 belongs to a family of structurally-related toll-like receptors (TLRs) containing an N-terminal domain rich in leucine repeats and a C-terminal intracellular Toll/interleukin (IL)-1 (TIL) domain. TLR-3 is expressed primarily in dendritic cells of the placenta and pancreas where it can reside on both sides of the plasma membrane and in the endosomal compartment of the cells. Recombinant human TLR-3 is 77.0 kDa glycoprotein containing 681 residues which comprise the TLR-3 extracellular domain.
Specifications
Additional Names
Toll-like receptor 3; CD283 antigen
Preparation
Biological activity was determined by its ability to inhibit IL - 8 secretion induced by Poly I:C in the TLR3 receptor - expressing HEK293 cells (HEK293 TLR3r).The ED50 for this effect is ? 30 μg/ml in the presence of 100 μg/ml of Poly I:C.

Storage
The lyophilized TLR-3 recombinant protein is stable for at least 2 years from date of receipt at -20ËšC. Reconstituted TLR-3 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20ËšC. As with any protein, exposing TLR-3 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
