Human CellExp™ TLR-3, Human Recombinant
Promotes the NF-kB pathway to initiate innate and adaptive immune responses
Product Overview
Product Name: TLR-3, Human CellExp™, Human Recombinant
Alternate Name/Synonyms: Toll-like receptor 3; CD283 antigen
Gene Symbol: TLR3
Accession #: O15455
Gene ID: 7098
Source: HEK 293 cells
Appearance: Lyophilized powder
Physical Form Description: Sterile filtered through a 0.2 micron filter. Lyophilized from 20 mM Sodium Phosphate, pH 7.5.
Molecular Weight: 77.4 kDa
Purity by SDS-PAGE: ≥95%
Purity by HPLC: N/A
Endotoxin Level: < 0.1 ng/μg of protein (<1EU/μg).
Biological Activity: 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.
Reconstitution Instructions: Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
Storage Temp.: -20°C
Shipping: Gel pack
Background Information: 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 77.4 kDa glycoprotein containing 681 residues which comprise the TLR-3 extracellular domain.
