short description

The Bioaim Human Eotaxin-1 ELISA kit is a solid phase sandwich ELISA (enzyme-linked immunosorbent assay) for the quantitative measurement of Eotaxin-1 in Human serum, plasma and cell culture media. An antibody specific for Human Eotaxin-1 was coated on a 96-well plate. Standards and samples are added to the wells and any Eotaxin-1 present binds to the immobilized antibody. The wells are washed and biotinylated anti-Human Eotaxin-1 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 Eotaxin-1 present in the initial sample. The Stop Solution changes the color from blue to yellow, and the microwell absorbances are read at 450 nm.

C-C motif chemokine ligand 11 (Eotaxin)
Background: CCL11/Eotaxin is a chemokine that interacts with CCR3 to induce eosinophil, basophil, dendritic cell, and Th2 cell chemoattraction during inflammatory and allergic reactions. Its production is upregulated in airway epithelium, alveolar macrophages, eosinophils, smooth muscle cells, chondrocytes, and fibroblasts following allergen or inflammatory challenge. CCL11 is also involved in the growth of myeloid cell progenitors and the differentiation of mast cells. CCL11 selectively recruits eosinophils by inducing their chemotaxis, and therefore, is implicated in allergic responses. The effects of CCL11 are mediated by its binding to a G-protein-linked receptor known as a chemokine receptor. Chemokine receptors include CCR2, CCR3 and CCR5. However, it has been found that eotaxin-1 (CCL11) has high degree selectivity for its receptor, such that they are inactive on neutrophils and monocytes, which do not express CCR3.
