Elafin, Human, ELISA kit
背景资料:The human elafin 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 elafin· 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 elafin standards (log)· The human elafin concentration of samples, which are run concurrently with the standards, can be determined from the standard curve。
产品描述:Elafin is an epithelial proteinase inhibitor also known under various other names such as Skin-derived Anti leukoproteinase (SKALP) and Elastase-Specific Inhibitor (ESI)· Elafin belongs to the Trappin gene family and was given the systematic name Trappin-2 in a recent classification· The Trappin family is defined by a N-terminal transglutaminase substrate domain and a C-terminal four disulphide core· Trappins have been suggested to play a role in the regulation of inflammation and in protection against tissue damage in stratified epithelia· Elafin is an inhibitor of leukocyte elastase and proteinase-3 and in addition it is a substrate for transglutaminases· The protein is constitutively expressed in various epithelia including those of hair follicles, oesophagus, vagina and oral cavity· Elafin is not present in normal human skin but is strongly induced during inflammation as in psoriasis and wound healing· The full-length protein is translated as a 12·3 kDa protein of 117 amino acids termed pre-elafin or Trappin-2· Cleavage of the signal peptide yields a mature protein with a molecular mass of 9·9 kDa· The 9·9 kDa secreted protein is the major form found in culture medium· In skin extracts a 6 kDa form comprising the 57 most C-terminal amino acids is present, which is the form of elafin originally described by Wiedow et al· In serum both the 9·9 and the 6 kDa form appear to be present· In urine only the short 6 kDa form is found· The HYCULT BIOTECH ELISA is not suitable to measure the short 6 kDa form· Elafin has been used as a quantitative marker for disease activity in severe psoriasis during treatment with cyclosporin· In serum/plasma of healthy individuals approximately 10-50 ng/ml elafin is present· Elafin shows a 10-fold increase in concentration during psoriasis· The determination of lafine is not disturbed by the presence of the short 6 kDa form·。

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。 |
