Our Abpromise guarantee covers the use of ab16894 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
Functional Studies Use at an assay dependent concentration.

Mice were injected i.p. with 1 mg ab16894, after 1 hour incubation mice were challenged; 5 µg/ml was added to cell culture.

ICC/IF Use at an assay dependent concentration.
WB Use at an assay dependent concentration. PubMed: 25404049
IP Use at an assay dependent concentration.

40 µg cleared protein was incubated with 2 µg ab16894 for 1 hour at 4 °C.

Flow Cyt Use at an assay dependent concentration.

ab170190 - Mouse monoclonal IgG1, is suitable for use as an isotype control with this antibody.

4 x 104 leukocytes/ml were stained for 30 minutes at 4 °C.


IHC-Fr Use at an assay dependent concentration.

6 µm sections were fixed with acetone. Sections were blocked with goat serum and exposed overnight.


  • 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.

    Observed band size: 89 kDa
    why is the actual band size different from the predicted?
    Additional bands at: 60 kDa, 65 kDa. We are unsure as to the identity of these extra bands.
