    小鼠单克隆抗体[76B357.1] to TLR4
  • 特异性TLR4 expression levels and cleavage or degradation products can vary between different cell and tissue samples. Customers have observed this variability in WB band size and our laboratory has confirmed this variability as well observing lower molecular weight cleavage and degradation products and in some samples a lack of the full length TLR4 band. The TLR4 cleavage and degradation products and potential lack of full length TLR4 are well documented in the literature, including PMID 16885150 and 22927440. We recommend running a positive control human intestine tissue lysate.

  • 功能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.
  • 组织特异性Highly expressed in placenta, spleen and peripheral blood leukocytes. Detected in monocytes, macrophages, dendritic cells and several types of T-cells.
  • 疾病相关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.
  • 序列相似性Belongs to the Toll-like receptor family.
    Contains 18 LRR (leucine-rich) repeats.
    Contains 1 LRRCT domain.
    Contains 1 TIR domain.
  • 结构域The TIR domain mediates interaction with NOX4.
  • 翻译后修饰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.

  • ab22048 staining TLR4 in Human stomach tissue sections by Immunohistochemistry (IHC-P - formaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde and blocked with 5% serum for 1 hour; antigen retrieval was by heat mediation in citrate buffer (10mM, pH 6) (ab64236). Samples were incubated with primary antibody (1/100) for 1 hour at 23°C. An undiluted HRP-conjugated goat anti-mouse IgG polyclonal was used as the secondary antibody.

  • ab22048 staining TLR4 in Mouse spleen tissue sections by Immunohistochemistry (IHC-Fr - frozen sections). Tissue was fixed with acetone and blocked with 10% serum for 30 minutes at 20°C. Samples were incubated with primary antibody (1/100 in PBS-BSA) for 1 hour at 20°C. An Alexa Fluor®488-conjugated Rat anti mouse IgG polyclonal (1/200) was used as the secondary antibody.

    TLR4 labelling (yellow) co-localises with CD35 labelling (red) on follicular dendritic cells in the spleen.  TLR 4 alone (green) can also be seen on other cell types in the spleen- most probably macrophages.

  • Overlay histogram showing Jurkat cells (ab7899) stained with ab22048 (red line). The cells were fixed with methanol (5 min) and incubated in 1x PBS / 10% normal goat serum (ab7481) / 0.3M glycine to block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab22048, 1µg/1x106 cells) for 30 min at 22°C. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22°C. Isotype control antibody (black line) was mouse IgG2b [PLPV219] (ab91366, 2µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed. This antibody gave a positive signal in Jurkat cells fixed with 4% paraformaldehyde (10 min) used under the same conditions.

    Please note that Abcam do not have data for use of this antibody on non-fixed cells. We welcome any customer feedback.

  • Immunofluorescence analysis of murine macrophages, staining TLR4 with ab22048.

    Cells were fixed with formaldehyde, permeabilized with 0.1% Triton X-100 and blocked with 1% BSA for 10 minutes at 25°C. Samples were incubated with primary antibody (1/100 in 1% BSA) for 12 hours at 4°C. A TexasRed®-conjugated donkey anti-mouse (ab6818) polyclonal IgG (1/100) was used as the secondary antibody.

  • ab22048 (5 ug/ml) staining TLR4 in Human skin tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Membrane-cytoplasmic immunopositivity of TLR4 was primarily observed in the pigmented basel cells and the adjacent keratinocytes in the epidermal layer.
