Product details

Human TLR2 ELISA Kit (ab227897) is a single-wash 90 min sandwich ELISA designed for the quantitative measurement of TLR2 protein in cit plasma, edta plasma, hep plasma, milk, serum, urine, and cell lysate. It uses our proprietary SimpleStep ELISA® technology. Quantitate Human TLR2 with 17 pg/ml sensitivity.

SimpleStep ELISA® technology employs capture antibodies conjugated to an affinity tag that is recognized by the monoclonal antibody used to coat our SimpleStep ELISA® plates. This approach to sandwich ELISA allows the formation of the antibody-analyte sandwich complex in a single step, significantly reducing assay time. See the SimpleStep ELISA® protocol summary in the image section for further details. Our SimpleStep ELISA® technology provides several benefits:

- Single-wash protocol reduces assay time to 90 minutes or less
- High sensitivity, specificity and reproducibility from superior antibodies
- Fully validated in biological samples
- 96-wells plate breakable into 12 x 8 wells strips

A 384-well SimpleStep ELISA® microplate (ab203359) is available to use as an alternative to the 96-well microplate provided with SimpleStep ELISA® kits.

The standard is affinity purified.

Supplementary information

Toll-like receptor 2 (TLR2) also called CD282 is a protein that detects molecules from bacteria and fungi. It has a mass of about 90 kDa. TLR2 is expressed on the surface of immune cells such as monocytes macrophages and neutrophils. This receptor recognizes pathogen-associated molecular patterns (PAMPs) and activates the immune response.

Biological function summary

TLR2 initiates signaling pathways that lead to the production of cytokines and chemokines helping to control infection. It forms dimers with other TLRs like TLR1 or TLR6 to expand its recognition range of microbial components. TLR2's activity is important for balancing pathogen recognition and avoiding overactive immune response. On macrophages TLR2 activation enhances their phagocytic ability.

Pathways

TLR2 plays roles in innate immune signaling pathways and inflammation pathways. It contributes significantly to the NF-kB and MAPK pathways which regulate inflammation and immune response. TLR2 often cooperates with proteins like MyD88 and TRAF6 in these pathways leading to downstream activation of transcription factors and production of pro-inflammatory molecules.

TLR2 is associated with inflammatory and infectious diseases including sepsis and tuberculosis. During tuberculosis interactions between TLR2 and its ligands trigger immune responses that are important for bacterial control. Additionally TLR2’s overactivation links to sepsis by causing excessive inflammation. Researchers study TLR2 for potential therapeutic targeting in these diseases assessing how modulation can improve outcomes or reduce detrimental inflammation.

Target data

Cooperates with LY96 to mediate the innate immune response to bacterial lipoproteins and other microbial cell wall components. Cooperates with TLR1 or TLR6 to mediate the innate immune response to bacterial lipoproteins or lipopeptides (PubMed : 17889651, PubMed : 21078852). Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. May also activate immune cells and promote apoptosis in response to the lipid moiety of lipoproteins (PubMed : 10426995, PubMed : 10426996). Recognizes mycoplasmal macrophage-activating lipopeptide-2kD (MALP-2), soluble tuberculosis factor (STF), phenol-soluble modulin (PSM) and B.burgdorferi outer surface protein A lipoprotein (OspA-L) cooperatively with TLR6 (PubMed : 11441107). Stimulation of monocytes in vitro with M.tuberculosis PstS1 induces p38 MAPK and ERK1/2 activation primarily via this receptor, but also partially via TLR4 (PubMed : 16622205). MAPK activation in response to bacterial peptidoglycan also occurs via this receptor (PubMed : 16622205). Acts as a receptor for M.tuberculosis lipoproteins LprA, LprG, LpqH and PstS1, some lipoproteins are dependent on other coreceptors (TLR1, CD14 and/or CD36); the lipoproteins act as agonists to modulate antigen presenting cell functions in response to the pathogen (PubMed : 19362712). M.tuberculosis HSP70 (dnaK) but not HSP65 (groEL-2) acts via this protein to stimulate NF-kappa-B expression (PubMed : 15809303). Recognizes M.tuberculosis major T-antigen EsxA (ESAT-6) which inhibits downstream MYD88-dependent signaling (shown in mouse) (By similarity). Forms activation clusters composed of several receptors depending on the ligand, these clusters trigger signaling from the cell surface and subsequently are targeted to the Golgi in a lipid-raft dependent pathway. Forms the cluster TLR2 : TLR6 : CD14 : CD36 in response to diacylated lipopeptides and TLR2 : TLR1 : CD14 in response to triacylated lipopeptides (PubMed : 16880211). Required for normal uptake of M.tuberculosis, a process that is inhibited by M.tuberculosis LppM (By similarity).
