LightSwitch™ 3´UTR GoClone™ 货号：E-32011
LightSwitch™ 3´UTR Reporter GoClone™ Collection
背景资料：The LightSwitch™ Luciferase Assay System includes over 30,000 regulatory elements from the human genome that have been cloned into LightSwitch reporter vectors. With pre-cloned human promoters, lncRNA promoters and 3´UTRs available as transfection-ready LightSwitch luciferase reporter constructs, you can perform your reporter assay experiments immediately. The LightSwitch System makes it easy for you to measure the transcriptional and post-transcription regulation of any gene in the genome.
To ensure high-quality results, LightSwitch reporter vectors utilize a novel, engineered luciferase gene (RenSP) and optimized reagents that provide industry-leading sensitivity. For more information, please see the tabs below as well as the Overviewand RenSP Luciferase sections on the LightSwitch Luciferase Assay System page.

Post transcriptional regulation through miRNA-3´UTR interactions
Gene regulation studies have historically focused on events that influence transcription, such as the binding of transcription factors to promoters. More recently, much research has centered on the presence or absence of histone modifications that alter the chromatin structure, which influences DNA accessibility and its ability to be transcribed. However, post-transcriptionalevents play an equally important role in gene regulation.
MicroRNAs (miRNAs) are small, non-coding RNA molecules of approximately 22 nucleotides that play a large role as post-transcriptional regulators. miRNAs are thought to repress expression by targeting the 3´UTR (untranslated) region of mRNA transcripts. The interaction of a miRNA with a 3´UTR results in either increased degradation of the target transcript or inhibition of translation.
While the human genome is thought to encode only about 1000 miRNAs, they are believed to target ~60% of mRNA transcripts. A given miRNA may have multiple 3´UTR targets, and a given 3´UTR may be targeted by multiple miRNAs. Therefore, there is considerable interest in studying miRNA-3´UTR interactions.
LightSwitch products for the study of 3´UTR-miRNA interactions
LightSwitch 3´UTR Reporter constructs are ideal for performing miRNA target validation, as well as assessing the functional impact of miRNA-3´UTR interactions. In combination with our miRNA Mimics and Inhibitors, which are co-transfected with the 3´UTR Reporter constructs (Figure 1), you have everything needed to validate miRNA targets, measure RNA stability, translation efficiency and the functional impact of miRNAs on a gene-by-gene basis. We also offer over 900 optimized LightSwitch Synthetic miRNA Target Reporter constructs, which can provide increased response relative to the endogenous sequences cloned into the LightSwitch 3´UTR Reporter constructs.
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。 |
