C5a(人)ELISA试剂盒 货号:E-HK349
C5a, Human, ELISA kit
背景资料:The human C5a 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 incubated in microtiter wells coated with antibodies recognizing human C5a· Biotinylated tracer antibody will bind to the captured human C5a· 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 oxalic 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 C5a standards (log)· The human C5a concentration of samples, which are run concurrently with the standards, can be determined from the standard curve··
产品描述:The complement system is an important factor in innate immunity· During complement activation of complement protein 5 (C5), C5 is proteolytically cleaved and the anaphylatoxic peptide C5a is generated· C5a is a small polypeptide consisting of 74 aminoacids (11kDa) and is derived from the N-terminus of the alpha chain· C5a itself is very short-lived and in serum is cleaved rapidly into the more stable, though biologically still active C5a-desArg (also called acylation stimulating protein, ASP· Therefore, measurement of C5a-desArg allows reliable conclusions about the level of complement activation in the test samples· For convenience, both forms will be referred to in the following text as C5a· C5a acts as a potent anaphylatoxin causing smooth muscle contraction, vasodilation, increased vascular permeability, basophil and mast cell degranulation and lysosomal enzyme release· In addition, C5a is a potent chemotactic factor for eosinophils, basophils and monocytes·
产品特点:Human C5a can be measured accurately if serum or plasma samples are diluted at least 4x and For activated serum human C5a can be measured accurately if serum samples are diluted at least 100x·Human C5a can be measured accurately if CSF samples are diluted at least 2x and if sputum samples are diluted at least 2x · The cross reactivity with Human C3a was negative·
保存建议:推荐4℃保存,有效期一年。

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。 |
