SAP, Mouse, ELISA kit

背景资料:The mouse SAP 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 a plate 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 mouse SAP· Biotinylated tracer antibody will bind to the captured mouse SAP· 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 mouse SAP standards (log)· The mouse SAP concentration of samples, which are run concurrently with the standards, can be determined from the standard curve·

产品描述: Serum amyloid P component (SAP) belongs to a highly conserved superfamily of calcium-dependent ligand binding and lectin (carbohydrate binding) proteins, also called pentraxins, due to the pentameric structure of the proteins· The polypeptide subunits are 31 kDa in size under reducing conditions· The C-reactive protein (CRP) and SAP are short pentraxins, which are produced in the liver in response to inflammatory mediators· Pentraxin 3 (PTX3), is the prototypic long pentraxin· Both SAP and CRP are evolutionary conserved in all vertebrates and also found in distant invertebrates such as the horseshoe crab (Limulus polyphemus)· Human SAP and CRP share 51% residue sequence identity and 66% homology· Mouse SAP has shown to be a reliable marker of the acute phase· In mouse, SAP levels increase significantly 24 hours after challenge with lipopolysaccharide· In man, SAP does not become elevated during inflammation, whereas CRP is the prototypical acute phase reactant· CRP in mice has been isolated, but it has not been well documented as it occurs only at concentrations of nanograms per milliliter· SAP is highly resistant to proteolysis, especially when it forms complexes with calcium-dependent ligands· SAP avidly binds to macromolecular ligands, such as nucleosomal DNA, glycosaminoglycans and amyloid fibrils· Aggregated SAP can bind C1q and activate the classical complement pathway· SAP contributes significantly to the pathogenesis of amyloidosis· The mechanism of its participation is not yet known and may differ between species· The normal mouse serum level of SAP is similar between males and females, but is different among mouse strains· Endogenous SAP levels range from 20 ug/ml to 150 ug/ml· Mouse strains can be divided in high and low SAP-responder strains after stimulation·

产品特点:Detection level 0·4 ng-ml

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。
