EndoCab, IgA(人)ELISA试剂盒                                            货号:E-HK504-IgA

EndoCab, IgA, Human, ELISA kit

背景资料:The EndoCab IgA ELISA is a ready-to-use solid-phase enzyme-linked immunosorbent assay based on the sandwich principle with a working time of 2·5 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 equimolar amounts of endotoxin rough-lipopolysaccharides from four Gram-negative bacterial species, each comprised of a complete inner core, but lacking complete outer core or O-specific polysaccharide chain· Anti-endotoxin-core antibodies are captured by the solid phase antigen· Peroxidase conjugated anti-human IgA antibody will bind to captured endotoxin-core antibodies· The peroxidase conjugated antibody 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 Endocab IgA standards (log)· The endotoxin-core concentration of samples, which are run concurrently with the standards, can be determined from the standard curve··

产品描述:The EndoCab IgA ELISA has been developed for determination of endotoxin core antibodies in human plasma or serum in patients or healthy individuals· Several studies show a consistent drop in postoperative levels of circulating anti-endotoxin core antibodies compared to the preoperative value· This drop has been interpreted as consumption of antibodies to endotoxin by systemic release of endotoxin· A hypothesis is that if the patients pre-operative endotoxin-core level is low, even moderately low, patients may not be able to cope with the efflux of endotoxin, which may have mild to severe clinical consequences· The assay is of interest for various experimental conditions ranging from in vitro LPS neutralization by plasma components to in vivo studies on kinetics of antibodies to endotoxin in health and diseases· The EndoCab standard median-units IgA (MU) are arbitrary and are based on medians of ranges for 1000 healthy adults in a particular locality· It has not been established whether normal endotoxin-core antibody values vary by region, culture or race· Users should establish appropriate local statistical controls for their studies· It is advised that studies of any patient group should always be controled by studies of appropriately selected contrasting clinical groups and/or healthy individuals recruited locally· EndoCab is a registered trademark· Used under license from the Scottish National Blood Transfusion Service··

产品特点:The EndoCab IgA ELISA kit is to be used for the in vitro quantitative determination of endotoxin-core antibodies in serum, plasma and cell culture supernatant·

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。
