ICFC - Quality tested

Application Notes:

Additional reported application (for the relevant formats) include: immunohistochemical staining of frozen tissue1.

Recommended Usage:

Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.125 µg per million cells in 100 µl volume.  It is recommended that the reagent be titrated for optimal performance for each application.

C57BL/6 mouse splenocytes were surface

C57BL/6 mouse splenocytes were surface stained with CD4/CD19/Ly-6G/NK1.1 PerCP, CD11c APC and CD8 FITC, followed by intracellular staining with TLR3 (clone 11F8) PE (top) or rat IgG2a, κ PE isotype control (bottom). The data was analyzed by gating on CD4/CD19/Ly-6G/NK1.1 negative and CD8 positive cells.


Toll-like receptor 3 (TLR3), also known as CD283, is type I transmembrane protein that belongs to the TLR family. It forms a large horseshoe shape that contacts a neighboring horseshoe, forming a dimer of two horseshoes. It is characterized by an extracellular domain with leucine-rich repeats and a cytoplasmic domain with homology to the type I IL-1 receptor. TLR3 is expressed selectively on the cytoplasmic membrane and intracellularly in dendritic cells. It is also highly expressed in the placenta, pancreas, heart, liver, lung, and muscle. TLR3 is a pattern recognition receptor that participates in innate immune response to microbial pathogens by recognizing polyinosine-polycytidylic acid (Poly(I:C)) and dsRNA. Ligand binding by TLR3 induces receptor dimerization which results in inducing NF-κB activation (via TRIF-linked RIP1/TLR3 interactions) and cytokine production. TLR3 has been shown to interact with a number of proteins including MYD88, TRAF6, TRIAD3, MAP3K7, and TAB2.

Other Names: Toll like receptor 3
Structure: Toll-like receptor family member; type I membrane protein containing multiple leucine repeats and a interleukin-1 receptor like region in the extracellular domain. Predicted molecular weight approximately 116 kD.
Distribution: Selective expression in dendritic cells. Highly expressed in placenta and the pancreas; also expressed in heart, liver, lung and muscle.
Function: Pattern recognition receptor that participates in innate immune response to microbial pathogens. TLR3 ligands induce NF-κB (via TRIF-linked RIP1/TLR3 interactions) and cytokine production. TLR3 stimulation results in the production of cytokines.
Ligand Receptor: Polyinosine-polycytidylic acid (Poly(I:C)), dsRNA.
Interaction: MYD88, TRAF6, TRIAD3, MAP3K7, and TAB2.
