  • Product overview

    TLR2 in vitro SimpleStep ELISA® (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of TLR2 protein in Mouse serum, plasma, cell culture media, cell and tissue extract.

    The SimpleStep ELISA® employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.

    Toll-Like Receptor 2 (TLR2) is a transmembrane receptor, expressed on a wide variety of cell types including microglia, monocytes, macrophages, and dendritic cells. TLR2 cooperates with multiple other proteins (TLR1, LY96, TLR6, and other) to mediate an immune response to bacterial lipoproteins. Cytokine secretion in response to these bacterium is found to occur in a TLR2 dependent fashion. Ab224880 recognizes the extracellular domain of the transmembrane receptor.

  • Research areas

  • Function

    Cooperates with LY96 to mediate the innate immune response to bacterial lipoproteins and other microbial cell wall components. Cooperates with TLR1 to mediate the innate immune response to bacterial lipoproteins or lipopeptides. Acts via MYD88 and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. May also promote apoptosis in response to lipoproteins. 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.
  • Tissue specificity

    Highly expressed in peripheral blood leukocytes, in particular in monocytes, in bone marrow, lymph node and in spleen. Also detected in lung and in fetal liver. Levels are low in other tissues.
  • Sequence similarities

    Belongs to the Toll-like receptor family.
    Contains 14 LRR (leucine-rich) repeats.
    Contains 1 TIR domain.
  • Post-translational

    Glycosylation of Asn-442 is critical for secretion of the N-terminal ectodomain of TLR2.

  • The concentrations of TLR2 were measured in duplicates, interpolated from the TLR2 standard curves and corrected for sample dilution. Undiluted samples are as follows: serum 12.5%, plasma (citrate) 12.5%, plasma (EDTA) 12.5%, and plasma (heparin) 12.5%. The interpolated dilution factor corrected values are plotted (mean +/- SD, n=2).
