The Human Endostatin ELISA quantitates Hu Endostatin in human serum, plasma, or cell culture medium. The assay will exclusively recognize both natural and recombinant Hu Endostatin.
原理方法
The Human Endostatin 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.
严格验证
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.
Endostatin is able to avoke non-uniform response for proliferation, cell mount and migration of entothelial cells, which different endostatin binding characteristic, leads to the assumption that endostatin effect is strongly dependent from endothelial cell type. Furthermore endostatin inhibits angiogenesis and tumor growth in vivo by inducing apoptosis in endothelial cells. The local delivery of endostatin seems to specifically affect tumor-associated microvessels by reduction of the vessel density, diameter and functionality. Tumor cell migration and invasion was greatly reduced in the endostatin treated animals. Endostatin is non-toxic and does not induce aquired drug resistance and has therefor become a potent new therapy strategy in solid neoplasias. This therapy appears to have a high potential not only for the treatment of gliomas, the most common brain tumors, but also in other tumors. The ability of endostatin to inhibit neoangiogenesis is mediated, at least in part, by Zn^+2 binding and elastase processing. Widespread endostatin expression was found in elactic fibers in vessel walls and in some other basement membrane zones. Endostatin is released by neurons to accumulate in amyloid plaques in Alzheimer's disease.
