[Abstract]  Paper nanobiosensors have been established as an excellent platform for analysis of veterinary and human pathogens causing various diseases. Especially, lateral flow assays or biosensors ideal for sensitive, rapid, robust and accurate analysis in laboratory setups and on-site analysis. Viral RNA detection is of great importance for public health as well as animal health protection. In that aspect, the present protocol focuses on the development of functionalized gold nanoparticle-based lateral flow biosensor for fish nervous necrosis virus (Nodavirus) nucleic acids detection. Total viral RNA, ... [摘要]  [摘要] 纸纳米生物传感器已经成为分析导致各种疾病的兽医和人类病原体的一个极好的平台。尤其是侧向流分析或生物传感器是实验室设备和现场分析中灵敏、快速、可靠和准确分析的理想选择。病毒RNA检测对公共卫生和动物健康保护具有重要意义。在这一方面,本协议的重点是开发功能化金纳米粒子侧流生物传感器,用于鱼类神经坏死病毒(Nodavirus)核酸检测。从鱼类标本中分离出的总病毒RNA进行逆转录PCR扩增,扩增产物与特异性寡核苷酸探针混合。当有nodavirus产物存在时,形成红色检测线。这种方法对基础研究有很大的意义,因为它消除了耗时、繁琐的电泳程序的需要,并且可以在养鱼场对养鱼户进行调整。利用这种生物分析平台进行病害监测,无需耗费大量时间和成本,对水产养殖和环境安全有很大影响。

[背景] 关注点和/或现场生物分析一直是关注人类和动物福祉的研究工作的最终目标。基于纸基的传感平台具有功能化简单、重现性好、制造成本低等优点,是一种极具吸引力的分析平台。纸基分析设备已应用于小分子、蛋白质和各种核酸的分析(Parolo和Merkoçi,2013;Bahadir和Sezgintürk,2016;Jiang等人,2019)。侧流生物传感器(LFB)是一种带有干试剂的预制材料条带,通过流体样品激活。它们专为一次性一次性使用而设计,只要有足够的开/关信号(Posthuma ...

Detection of Transposable Element Insertion Site Polymorphisms by Sequence-Specific Amplification Polymorphism (SSAP)

[Abstract]  Transposable elements represent a major part of any eukaryotic genomes. Notably in plants they can account for more than 80% of the whole genomic sequence (such as in maize). Due to their mobility across the genome, they can act as mutagens but can also be considered as an important source of genetic diversity. It has been shown that they may be activated following various stresses, and it has been assumed that they may contribute to genome evolution and adaptation. Molecular methods have thus been proposed to allow identification of new transposition events, or more generally to tag ... [摘要]  转座元件代表任何真核基因组的主要部分。值得注意的是,在植物中,它们可以占全部基因组序列的80%以上(例如在玉米中)。由于它们在基因组上的移动性,它们可以作为诱变剂,但也可以被认为是遗传多样性的重要来源。已经表明,它们可以在各种胁迫之后被激活,并且已经假定它们可以有助于基因组进化和适应。因此已经提出分子方法以允许鉴定新的转座事件,或更通常地标记可转座元件插入位点多态性。序列特异性扩增多态性(SSAP)是源自AFLP的高通量方法,其已经在大麦基因组上首先测试(Waugh等人,1997)。与AFLP相比,其标记TE的效率基于锚定在感兴趣的TE序列中的特异性引物的使用,需要先前表征所调查的TE。 SSAP因此可以用于鉴定TE插入位点附近的任何基因组重组,并且仍然是分析TE的进化动力学的有效方法。
