About This Kit
The Human CXCR4 ELISA quantitates CXCR4 in serum, plasma, and other biological fluids
The Human CXCR4 (Chemokine C-X-C-Motif Receptor 4) solid-phase sandwich ELISA (enzyme-linked immunosorbent assay) is designed to measure the amount of the target bound between a matched antibody pair. A target-specific antibody has been pre-coated in the wells of the supplied microplate. Samples are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the binding of the second (detector) antibody to the target on a different epitope from the capture antibody. An antibody conjugated with enzyme binds the formed sandwich. After incubation and washing steps to rid the microplate of unbound substances, a substrate solution is added that reacts with the enzyme-antibody-target complex to produce measurable signal. The intensity of this signal is directly proportional to the concentration of target present in the original specimen.
Rigorous validation:
Each manufactured lot of this ELISA kit is quality tested for criteria such as sensitivity, specificity, precision, and lot-to-lot consistency. See manual for more information on validation.
Target information
CXCR4 (Fusin, LESTR, HUMSTR) is a member of the G-protein-coupled chemokine receptor family with seven membrane-spanning domains, and functions as a co-receptor for X4 HIV-1 entry into CD4+ cells. CXCR4 has been proved to be the co-receptor for HIV-2's binding to CD4 through envelope glycoprotein gp 120 and promotes Env-mediated fusion of the virus. In other cases, CXCR4 can even function as the only receptor for HIV-2's binding to the CD4 host cells. CXCR4 is the receptor for the C-X-C chemokine CXCL12/SDF-1 that transduces a signal by increasing intracellular calcium ion levels and enhancing MAPK1/MAPK3 activation. CXCR4 acts as a receptor for extracellular ubiquitin; leading to enhanced intracellular calcium ions and reduced cellular cAMP levels. Also, CXCR4 is involved in hematopoiesis and in cardiac ventricular septum formation, and plays an essential role in vascularization of the gastrointestinal tract, probably by regulating vascular branching and/or remodeling processes in endothelial cells. In the CNS, CXCR4 could mediate hippocampal-neuron survival and is involved in cerebellar development. CXCR4 binds bacterial lipopolysaccharide (LPS) and mediates LPS-induced inflammatory response, including TNF secretion by monocytes. Antibodies to CXCR4 block HIV-1 and HIV-2 fusion and infection of human target cells. The amino-terminal domain and the second extracellular loop of CXCR4 serve as HIV biding sites.
