About This Kit
The Human CD200 ELISA quantitates Hu CD200 in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu CD200.
Principle of the method
The Human CD200 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, standards, or controls are then added into these wells and bind to the immobilized (capture) antibody. The sandwich is formed by the addition of the second (detector) antibody, 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
CD200 is a type-1 membrane glycoprotein that contains two immunoglobulin domains, and belongs to the immunoglobulin superfamily. CD200 is a broadly distributed cell surface glycoprotein that interacts with a receptor on myeloid cells (CD200R) and is implicated in locally preventing macrophage activation. Distant, but recognizable, homologues of CD200 have been identified in many herpesviruses and poxviruses. Studies of the related genes in mouse and rat suggest that CD200 may regulate myeloid cell activity and delivers an inhibitory signal for the macrophage lineage in diverse tissues. Multiple alternatively spliced transcript variants that encode different isoforms of CD200 have been found. Diseases associated with CD200 dysfunction include Mantle Cell Lymphoma and Primary Hypertrophic Osteoarthropathy.
