DFHBI-1T IMAGES
A. Live-cell imaging of a COS7 cell expressing CGG60-Spinach2TM in the presence of either 20 µM DFHBI or DFHBI-1T. Images of the same cell were acquired using a 100 msec exposure with a GFP filter set. B. Quantification of average DFHBI-1T brightness of 10 cells expressing CGG60-SpinachTM normalized to the brightness of DFHBI.

Lucerna——活体胞内RNA示踪
绿色荧光蛋白的发现及其应用是生命科学研究*一个重要的里程碑,使得细胞内不可见的重要蛋白无所遁形,进而明确其功能与调控机制。相较于蛋白质,近年在细胞内还揭示了一大类重要的分子——非编码RNA,这类特殊的RNA不编码蛋白,但是其数目远较编码RNA(mRNAs)多,包括microRNAs, Piwi-interacting RNAs, termini-associated RNAs等。目前对这一类RNA的研究方兴未艾,因技术上缺乏关键的研究工具对其细胞内定位于功能了解知之甚少。
胞内RNA成像技术可能是非编码RNA研究领域取得突破的关键,与绿色荧光蛋白相似,在目的RNA上标记荧光分子可以使RNA在荧光显微镜下呈现,明确其胞内定位,进而通过分子互作或药理学等技术了解其功能。然而目前的常规RNA成像技术难以在活细胞上应用,并且有效性存在很大问题。针对这一难题,来自威斯康星大学的研究人员成立了Lucerna公司,并研发了一种*的基因编码系统用于活细胞内RNA的荧光标记。该系统利用一种可与绿色荧光蛋白媲美的RNA原件——Spinach(一种RNA与源于绿色荧光蛋白的荧光小分子结合体,可与目的RNA结合并发射荧光)使得在活细胞中实时成像目的RNA的动态机制。利用该系统,研究人员可望在RNA胞内转运,降解、毒性RNA聚焦以及其他RNA调控机制的研究中取得突破性进展。
Lucerna的研发团队拥有超过25年的RNA生物学研究、RNA适配体研发及荧光成像技术的相关经验,拥有多项RNA荧光适配体,并发表了大量高水平文献。相信凭借这些优势,Lucerna可为RNA研究人员提供的研究产品与解决方案。
