  • General notes

    Ab9105 is a TLR4 function blocking antibody that is useful for studies on the role of TLR4 as a receptor fpr LPS induced cytokine production by TLR4 bearing cells.



Our Abpromise guarantee covers the use of ab9105 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.


  • FunctionCooperates 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 specificityHighly expressed in placenta, spleen and peripheral blood leukocytes. Detected in monocytes, macrophages, dendritic cells and several types of T-cells.
  • Involvement in diseaseGenetic 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 similaritiesBelongs to the Toll-like receptor family.
    Contains 18 LRR (leucine-rich) repeats.
    Contains 1 LRRCT domain.
    Contains 1 TIR domain.
  • DomainThe TIR domain mediates interaction with NOX4.
  • Post-translational
    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.

Thank you for your enquiry. The antibody recognizes the mouse TLR4/MD2 complex and is not useful for detection of TLR4 or MD2 alone.
