The Toll-like receptor (TLR) family in mammal comprises a family of transmembrane proteins characterized by multiple copies of leucine rich repeats in the extracellular domain and IL-1 receptor motif in the cytoplasmic domain. Like its counterparts in Drosophila, TLRs signal through adaptor molecules (1) and could constitute an important and unrecognized component of innate immunity in humans. The TLR family is a phylogenetically conserved mediator of innate immunity that is essential for microbial recognition (2). TLRs characterized so far activate the MyD88/interleukin-1 receptor-associated kinase (IRAK) signaling pathway. Ten human homologs of TLRs (TLR1-10) have been described (3). TLR3 cDNA codes for a protein with approximate molecular weight of 120 kDa (4). TLR3 has a restricted expression pattern being expressed in dendritic cells (DC) (4-6). TLR3 mRNA expression was detected by in situ hybridization in DC and lymph nodes (6). The expression of TLR3 in a single cell type may indicate a specific role for this molecule in a restricted setting.

A synthetic peptide corresponding to amino acids 55-70 (VLNLTHNQLRRLPAAN)of human TLR3 was used as immunogen, Gen Bank no. gb|AAH59372.1|. Human TLR3 is an 870 amino acid protein.

Application Notes

TLR3 Antibody

Western blot analysis of TLR3 in lysates from A) untransfected 293, B) 293 cells transfected with human TLR3 cDNA, C) human intestine, D) placenta, E) heart and F) ovary using TLR3 antibody at 3 ug/ml . IMGENEX's goat anti-mouse HRP conjugate (IMGENEX, 20101) was used as secondary.

TLR3 Antibody IMG-315A

Intracellular flow analysis of TLR3 in human monocytes using 0.5 ug of IMG-315A. Shaded histogram represents monocytes without antibody; green represents isotype control (IMGENEX, 20109); red represents anti-TLR3 antibody. Goat anti-mouse IgG1 PE conjugate (BD) was used as secondary.


IHC analysis of TLR3 in (A) human gut lumen (longitudinal section, transverse region) using IMG-315A at 10 ug/ml (Data courtesy Dr. Elizabeth Furrie, University of Dundee) and mouse spleen tissue using isotype control (B) and IMG-315A (C) at 5 mg/ml.
