Product overview
Human TLR4 ELISA Kit (ab277392) is an in-vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human TLR4 in serum (human TLR4 concentration is low in normal serum and plasma samples, and may not be detectable in this assay), plasma and cell culture supernatants.
This assay employs an antibody specific for Human TLR4 coated on a 96-well plate. Standards and samples are pipetted into the wells and Human TLR4 present in a sample is bound to the wells by the immobilized antibody. The wells are washed, and biotinylated anti-Human TLR4 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of Human TLR4 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

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
modificationsN-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. -
