TNF-alpha(人)ELISA试剂盒 货号：C-HK307-02
TNF-alpha, Human, ELISA kit
背景资料：The human TNF-alpha ELISA is a ready-to-use solid-phase enzyme-linked immunosorbent assay based on the sandwich principle with a working time of 3·5 hours· The efficient format of 2 plates with twelve disposable 8-well strips allows free choice of batch size for the assay· Samples and standards are captured by a solid bound specific antibody· Biotinylated tracer antibody will bind to captured human TNF-alpha· Streptavidin-peroxidase conjugate will bind to the biotinylated tracer antibody· Streptavidin-peroxidase conjugate will react with the substrate, tetramethylbenzidine (TMB)· The enzyme reaction is stopped by the addition of citric acid· The absorbance at 450 nm is measured with a spectrophotometer· A standard curve is obtained by plotting the absorbance (linear) versus the corresponding concentrations of the human TNF-alpha standards (log)· The human TNF-alpha concentration of samples, which are run concurrently with the standards, can be determined from the standard curve。
产品描述：Tumor necrosis factor alpha (TNF-alpha), a homotrimeric 17 KD protein, is a potent mediator of inflammatory and metabolic functions· TNF-alpha was originally detected as a highly cytotoxic cytokine for tumor cells, it causes tumor necrosis in vivo and shows cytolytic activity against tumor cells in vitro· Furthermore, TNF-alpha has been implied as central mediator in shock induced by gram negative micro-organisms· The cytokine TNF is found to be a central mediator in many inflammatory and immunological processes: it can be induced by various products of micro-organisms and by various cytokines but it also induces on its turn the production of many cytokines· Signal transduction occurs via two types of TNF-receptors, the p55 (RI) and p75 (RII) TNF-receptors· The receptors differ strongly in their intra-cellular signaling pathways· The TNF-alpha trimer interacts with either of the two types of TNF-R leading to receptor cross-linking。
产品特点：Detection level 10 pg/ml。

关于5-hmC
5-hmC是近年来在动物组织中发现的，由胞嘧啶修饰而来。5-hmC在表观遗传学上的功能可能与5-甲基化胞嘧啶(5-mC)不同。尽管到现在为止还不确知其功能，有研究者猜测它在调控基因的表达与关闭过程中起着重要的作用。5-mC的发现让我们不得不重新评估DNA甲基信息，也不得不监测人类的健康组织和病理组织之间5-mC相对分布的差异。在EPI公司的MethylFlash技术之前，我们还没有发现任何直接的常规方法来检测5- hmC,以及区分5-hmC和5-mC
5-hmC 和 5-mC的区别
时下常用的DNA甲基化分析方法包括限制内切酶酶切和亚硫酸氢盐或MeDIP介导的MS-PCR和测序，这些技术都不适合用来检测5-hmC，因为它与5-mC事实上很难用这类方法区分开来。为了解决这个问题，EPIk研制了MethylFlash羟甲基化DNA定量试剂盒(荧光法)。本试剂盒提供了一种很经济的方法来检测5-羟甲基化胞嘧啶，并且区分5-hmC, 5-mC, 和 C，使得研究者能够重新评估他们的DNA甲基化信息，也能够在新样品中寻找DNA羟甲基化。 |
