Background
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). The TLR family is a phylogenetically conserved mediator of innate immunity that is essential for microbial recognition (2). Ten human homologs of TLRs (TLR1-10) have been described (3). Among this family of receptors, TLR2 and TLR4 have been most studied. These studies have suggested that TLR2 and TLR4 may serve as potential main mediators of LPS signaling (4,5). The TLR4 cDNA codes for a protein consisting of 799 amino acids with approximate molecular weight of 88 kDa (6). |
Antigen
This antibody was developed against a portion of amino acids 100-200 of human TLR4. |
Application Notes
The amino acid sequence used is 100% homologous in human, chimp, baboon, chinese hamster, and rat; 93% homologous in bovine and pig; 85% homologous in sheep and 78% homologous in cat, horse and mouse. |
