The Bioaim Human CD14 ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of CD14 in Human serum, plasma and cell culture media. An antibody specific for Human CD14 was coated on a 96-well plate. Standards and samples are added to the wells and any CD14 present binds to the immobilized antibody. The wells are washed and biotinylated anti-Human CD14 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is added to the wells. The wells are again washed and TMB substrate solution is added, which produces a blue color in direct proportion to the amount of CD14 present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.Research Area Pathogen infection;

CD14 molecule(CD14) Background: CD14 (cluster of differentiation 14), also known as CD14, is a human gene. The protein encoded by this gene is a component of the innate immune system. CD14 exists in two forms, one anchored to the membrane by a glycosylphosphatidylinositol tail (mCD14), the other a soluble form (sCD14). Soluble CD14 either appears after shedding of mCD14 (48 kDa) or is directly secreted from intracellular vesicles (56 kDa). CD14 is an acute phase glycoprotein that binds lipopolysaccharide endotoxins (LPS) from Gram-negative bacteria. It is primarily expressed on monocytes, macrophages, and neutrophils, and soluble forms can be secreted or shed from the cell surface. CD14 accepts LPS from its initial binding by LBP, and it can further transfer LPS to the TLR4/MD2 complex. LPS acctivation of TLR4 triggers inflammatory activation. CD14 also contributes to the response to TLR3 ligands, phosphoinositides, as well as the surfactant proteins SP-A and SP-D.
