[Abstract]  The establishment of the CRISPR/Cas9 technology in diatoms (Hopes et al., 2016; Nymark et al., 2016) enables a simple, inexpensive and effective way of introducing targeted alterations in the genomic DNA of this highly important group of eukaryotic phytoplankton. Diatoms are of interest as model microorganisms in a variety of areas ranging from oceanography to materials science, in nano- and environmental biotechnology, and are presently being investigated as a source of renewable carbon-neutral fuel and chemicals. Here we present a detailed protocol of how to perform CRISPR/Cas9 gene editing of the marine diatom Phaeodactylum tricornutum, including: 1) insertion of guide RNA target site in the diatom optimized CRISPR/Cas9 vector (pKS diaCas9-sgRNA), 2) ... [摘要]  在硅藻(Hopes ,2016; Nymark等人,2016)中建立了CRISPR / Cas9技术,使得能够简单,廉价和有效地引入目标 这个非常重要的真核浮游植物群的基因组DNA的改变。 硅藻在纳米和环境生物技术领域从海洋学到材料科学,各种领域的示范性微生物都是有意义的,目前正在作为可再生碳中和燃料和化学品的来源进行调查。 在这里,我们提出了如何进行海洋硅藻三角褐指藻CRISPR / Cas9基因编辑的详细方案,包括:1)在硅藻优化的CRISPR / Cas9载体(pKS diaCas9)中插入引导RNA靶位点 -sgRNA),2)用于将pKS diaCas9-sgRNA质粒导入P的生物弹道转化。 三分支毛细胞和3)基于高分辨率熔融的PCR测定以筛选CRISPR / Cas9诱导的突变。
【背景】CRISPR / Cas9系统已被证明是许多真核生物中非常有效和成功的基因组编辑系统,现在也包括微藻(Hopes等人,2016; Nymark等人)。 ,2016; Shin 等人,2016)。 CRISPR / Cas9系统包括引导RNA(gRNA)和称为Cas9的核酸酶(Sander and Joung,2014)。 这两个分子形成复合物,其中gRNA将复合物引导至感兴趣的靶标。 ...

[Abstract]  The binding and internalization of adeno-associated virus (AAV) is an important determinant of viral infectivity and tropism. The ability to dissect these two tightly connected cellular processes would allow better understanding and provide insight on virus entry and trafficking. In the following protocol, we describe a quantitative PCR (qPCR) based method to determine the amount of vector bound to the cell surface and the amount of subsequent virus internalization based on viral genome quantification. This protocol is optimized for studying AAV. Nevertheless, it can serve as a backbone for studying other viruses with careful modification. [摘要]  腺相关病毒(AAV)的结合和内化是病毒感染和向性的重要决定因素。 解决这两个紧密相连的细胞过程的能力将有助于更好地了解并提供有关病毒进入和贩运的洞察。 在以下协议中,我们描述了基于定量PCR(qPCR)的方法,以确定基于病毒基因组定量结合到细胞表面的载体的量和随后的病毒内化的量。 该协议针对研究AAV进行了优化。 然而,它可以作为研究其他病毒,仔细修改的骨干。
【背景】评估AAV生物学的研究通常使用转基因表达作为实验终点。 然而,AAV在到达细胞核并转导细胞之前必须成功导航的许多关键步骤。 因此,AAV感染途径中有多个不同的步骤可能会单独或共同破坏,导致改变的转导。 AAV结合和内化的评估是确定小分子细胞修饰,基于CRISPR的基因敲除,基于siRNA的基因敲除或其他实验程序后观察到的转导差异的原因的重要的第一步
