Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate XCL2 in samples. An antibody specific for XCL2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyXCL2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for XCL2 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of XCL2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:Chemokine (C motif) ligand 2 (XCL2) is a small cytokine belonging to the XC chemokine family that is highly related to another chemokine called XCL1.It is predominantly expressed in activated T cells, but can also be found at low levels in unstimulated cells. XCL2 induces chemotaxis of cells expressing the chemokine receptor XCR1.
Chemokines are a group of small (approximately 8 to 14 kD), mostly basic, structurally related molecules that regulate cell trafficking of various types of leukocytes through interactions with a subset of 7-transmembrane G protein-coupled receptors. Chemokines also play fundamental roles in the development, homeostasis, and function of the immune system, and they have effects on cells of the central nervous system as well as on endothelial cells involved in angiogenesis or angiostasis.
