The monoclonal antibody TL2.1 recognizes human Toll-like receptor 2 (TLR2, CD282). Toll-like receptors (TLR) are highly conserved throughout evolution and are involved in the innate defence to many pathogens. In Drosophila toll is required for the anti-fungal response, while the related 18-wheeler is involved in antibacterial defences. In mammals, TLRs are identified as type I transmembrane signaling receptors with pattern recognition capabilities. They have been implicated in the innate host defence to pathogens. TLR2 is expressed on macrophages, smooth muscle, lung, spleen, thymus, brain and adipose tissue. TLR2 has been identified as a receptor that is central to the innate immune response to lipoproteins of Gram-negative bacteria, several whole Gram-positive bacteria, as well as a receptor for peptidoglycan and lipoteichoic acid and other bacterial cell membrane products. A functional interaction between TLR2 and TLR6 in the cellular response to various bacterial products has been discovered. TLR2 cooperates with LY96 to mediate the innate immune response to bacterial lipoproteins and other microbial cell wall components. It cooperates with TLR1 to mediate te innate immune response to bacterial lipoproteins or lipopeptides. It acts via MYD88 and TRAF6, leading to NF-κ-B activation, cytokine secretion and the inflammatory response. TLR2 also promotes apoptosis in response to lipoproteins. Bacterial species as diverse as mycobacteria, spirochetes, mycoplasma, S. aureus, B Burgdorferi, T pallidum, M fermentans and Streptococcus pneumoniae have all been shown to mediate cellular activation via TLR2. The monoclonal antibody TL2.1 is a TLR2 function blocking antibody that is useful for studies on the role of TLR2 as a pattern recognition receptor in microbial products induced cytokine production by TLR2 bearing cells such as human peripheral blood mononuclear cells.

Application
Flow cytometry, Frozen sections, Functional studies, Immuno fluorescence, Immuno precipitation, Paraffin sections, Western blot

Application Notes
FC: 2  µg antibody per 300000 cells; untreated as well as 0.4 % formaldehyde fixed cells can be used; do not permeabilize the cells or use 4 % faraformaldehyde as fixative! (Ref 5)
IF: HMECs were fixed with 4% paraformaldehyde in PBS, permeabilized and blocked before staining; antibody concentration used 5-10 µg/ml
W: peripheral blood mononuclear cells; non-reduced; 1  µg/ml antibody; size ~90 kDa
F: fixed in acetone; 3 % H2O2 for blockade of endogenous peroxidases; human tonsils as positive control (useful, but clone TL2.3 (HM2066) is preferred; Ref 2)
P: HOPE-fixed;alveolar epithelial cells type II in human lung as positive control; 1  µg/ml antibody for 16 hr at 4  °C (Ref 4)
IP: lysed monocytes were immunoprecipitated with antibody-conjugated Sepharose; size ~90 kDa (Ref 2)
FS: 1  µg/5x107 cells; antibody blocks TNFa release (induced by bacteria) from peripheral blood mononuclear cells (Ref 1)

Use
Dilutions to be used depend on detection system applied. It is recommended that users test the reagent and determine their own optimal dilutions. The typical starting working dilution is 1:50.

Positive Control
Peripheral blood mononuclear cells, granulocytes and monocytes.
