Recombinant Src protein
背景资料：The proto-oncogene tyrosine-protein kinase Src is a non-receptor protein tyrosine protein kinase that is involved in different signal transduction pathways that regulate such vital cellular processes as cell-cell interactions, cell migration, transcription and proliferation through the phosphorylation of many substrates. It is one of eight members of the Src family of non-receptor tyrosine kinases (Src, Fyn, Yes, Lck, Lyn, Hck, Fgr and Blk) that interact with the intracellular domains of growth factor/cytokine receptors, GPCRs and integrins. Members of the Src kinase family have a very similar domain structure with a high degree of homology in the SH1 (catalytic), linker, SH2 (p-Tyr binding), SH3 (protein-protein interaction) and SH4 (membrane association) domains. c-Src, Fyn and Yes are ubiquitously expressed, although high levels of c-Src are found in platelets, neural tissue and osteoclasts. The activity of the Src kinase family can also be regulated by phosphatases (e.g. SHP1), binding to adaptor proteins (e.g. CBP) and proteasomal degradation. Src kinases are key upstream mediators of both the PI 3-K and MAPK signaling pathways, and have been shown to have important roles in cell proliferation, migration and survival.
产品描述：
Recombinant human Src protein was produced using baculovirus infected Sf9 cells. The protein was made against amino acids M1-L536, accession number NM_005417 and N-terminally fused to GST-HIS6-Thrombin site. Purified by GSH-agarose affinity purification.
产品应用：
Recombinant Src is suitable for kinase assays and Western blot. The molecular weight of the protein is ~89.744 kDa. The activity of the protein is ~ 142 pmol/µg min. Recommended kinase reaction conditions: 60 mM HEPES-NaOH, pH 7.5, 3 mM MgCl2, 3 mM MnCl2, 3 µM Na-orthovanadate, 1.2 mM DTT, ATP (variable), 2.5 µg/50 µl PEG20.000, Substrate: PolyEY, 1 µg / 50 µl, Recombinant Src: 20 ng/50 µl. Kinase activity may vary depending on the substrate and reaction conditions used.
产品使用：
10 µg of Recombinant Src protein in 50 mM Tris-HCl, pH 8.0; 100 mM NaCl, 5 mM DTT, 15 mM reduced glutathione, 20% glycerol. Protein is supplied at 0.147 µg/µl.
温度保存：
Lyophilized proteins can be stored at -20°C or -80°C, preferably desiccated. Recombinant proteins in solution are temperature sensitive and must be stored at -80°C to prevent degradation. Avoid repeated freeze/thaw cycles and keep on ice when not in storage.

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。 |
