EndoClear迷你LAL实验包(红色): (EndoTrap red 1/1 + mini LAL)                       货号:E-HIT306

EndoClear, red, small (EndoTrap red 1/1 + mini LAL)

背景资料:Profos EndoTrap red assay (endotoxin removal): Binding capacity of 2,000,000 EU/ml· Endotoxin removal rates of >95% per cycle· Final LPS concentration 0·005 - 0·1 EU/ml· Column or batch mode· Operating at pH 6·0-9·0· Suitable for proteins, peptides and antibodies· Suitable for an ionic strength up to 250 mM NaCl (< 100 mM is recommended)· Suitable for LPS from Klebsiella pneumoniae and Serratia marcescens· Hycult Biotech Mini-LAL assay (endotoxin detection): Minimum concentration which can be measured is 0·01 EU/ml· Measurable endotoxin detection range of 0·01-10 EU/ml· Working volume of 50 ul/well· 72 determinations Operating at pH 6·5-8·0

产品描述:Bacterial endotoxin, lipopolysaccharide (LPS), is a fever-producing by-product of gram-negative bacteria commonly known as pyrogen· LPS consists of a polysaccharide, a core oligosaccharide and lipid A, which is responsible for the toxic effects· In human, lipopolysaccharide binding protein (LBP) plays a central role in response to LPS in the activation pathway and in the neutralization of LPS· Removal of endotoxin is one of the most difficult downstream processes during protein purification· EndoTrap red, as part of the EndoClear kit, is developed to meet the most challenging requirements of endotoxin removal: the highest endotoxin removal capacity combined with excellent recovery rates· EndoTrap red is based on affinity chromatography for column or batch mode· The working range of EndoTrap red is pH 6-9 and it works with an ionic strength up to 250 mM NaCl (<100 mM is recommended)· Proteins, peptides and antibodies can be applied onto the EndoTrap red column· LPS from Klebsiella pneumoniae and Serratia marcescens can only be removed with EndoTrap red· Besides the EndoTrap red, EndoTrap blue is also available· EndoTrap blue has a pH range of 4-9 and is capable to work with an ionic strength up to 600 mM· Endotoxin in plasmid can only be removed with EndoTrap blue· The detection of endotoxin is based on studies of Frederick Bang· He observed that bacteria caused intravascular coagulation in the American horseshoe crab, Limulus polyphemus· In collaboration, Levin and Bang found that the agent responsible for the clotting phenomena resided in the crab’s amoebocytes, or circulating blood cells, and that pyrogen triggers the turbidity and gel-forming reaction enzymatically· The Mini-LAL assay for endotoxin detection, the second part of the EndoClear kit, makes use of an activated enzyme· In the presence of a colorless substrate, the enzymatic reaction will cause a yellow colour to develop upon cleavage of the chromophore, p-nitroaniline (pNA)· The reaction is stopped by the addition of acetic acid and the absorbance at 405 nm is measured with a spectrophotometer· The endotoxin concentration of samples with unknown concentrations, which are run concurrently with the standards, can be determined from a standard curve 

产品特点:The EndoClear kit provides the opportunity to remove and detect endotoxin with just one kit· EndoClear consists of the Profos EndoTrap red assay (endotoxin removal) and the Hycult Biotech Mini-LAL assay (endotoxin detection)· The Profos EndoTrap red assay is intended for the removal of endotoxin with removal rates of >95% per cycle· The binding capacity of EndoTrap red is 2,000,000 EU/ml (1EU = 100 pg LPS)

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。
