Anti-TLR3 (Toll Like Receptor-3), Phycoerythrin conjugated, clone 4H271

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 TRL 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 120kD (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. Applications: Suitable for use in Western Blot and Flow Cytometry. Other applications have not been tested. Recommended Dilution: Western Blot: 1-3ug/ml, Flow Cytometry (Intercellular): 2-5 ug/1x10e6 cells, Optimal dilutions to be determined by the researcher. Positive Control: Human Intestine or Ramos, Storage and Stability: May be stored at 4°C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Freeze at -20°C. Aliquots are stable for at least 6 months at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
