  • General notes

    ab171260 has been reported for use in flow cytometric analysis. It has also been reported in blocking of LPS-induced cytokine production. For detection of peripheral monocytes, a three step staining protocol is recommended using purified anti-human TLR4 followed by biotin anti-mouse IgG and streptavidin-PE.

Properties

Applications

Our Abpromise guarantee covers the use of ab171260 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
Flow Cyt Use 1µg for 105-8 cells.

A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 µL.  It is highly recommended that for optimal staining of TLR4, whole blood be stained using the LWB protocol rather than Ficoll-gradient prepared PBMCs. The use of a density gradient appears to reduce the staining intensity significantly.
ab170191 - Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.

Functional Studies Use at an assay dependent concentration.

Target

  • Function
    Cooperates with LY96 and CD14 to mediate the innate immune response to bacterial lipopolysaccharide (LPS). Acts via MYD88, TIRAP and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. Also involved in LPS-independent inflammatory responses triggered by Ni(2+). These responses require non-conserved histidines and are, therefore, species-specific.
  • Tissue specificity
    Highly expressed in placenta, spleen and peripheral blood leukocytes. Detected in monocytes, macrophages, dendritic cells and several types of T-cells.
  • Involvement in disease
    Genetic variation in TLR4 is associated with age-related macular degeneration type 10 (ARMD10) [MIM:611488]. ARMD is a multifactorial eye disease and the most common cause of irreversible vision loss in the developed world. In most patients, the disease is manifest as ophthalmoscopically visible yellowish accumulations of protein and lipid that lie beneath the retinal pigment epithelium and within an elastin-containing structure known as Bruch membrane.
  • Sequence similarities
    Belongs to the Toll-like receptor family.
    Contains 18 LRR (leucine-rich) repeats.
    Contains 1 LRRCT domain.
    Contains 1 TIR domain.
  • Domain
    The TIR domain mediates interaction with NOX4.
  • Post-translational
    modifications
    N-glycosylated. Glycosylation of Asn-526 and Asn-575 seems to be necessary for the expression of TLR4 on the cell surface and the LPS-response. Likewise, mutants lacking two or more of the other N-glycosylation sites were deficient in interaction with LPS.
  • Cellular localization
    Membrane.
