[Abstract]  For both disease and basic science research, loss-of-function (LOF) mutations are vitally important. Herein, we provide a simple stream-lined protocol for generating LOF iPSC lines that circumvents the technical challenges of traditional gene-editing and cloning of established iPSC lines by combining the introduction of the CRISPR vector concurrently with episomal reprogramming plasmids into fibroblasts. Our experiments have produced nearly even numbers of all 3 genotypes in autosomal genes. In addition, we provide a detailed approach for maintaining and genotyping 96-well plates of iPSC ... [摘要]  对于疾病和基础科学研究而言,功能丧失(LOF)突变是非常重要的。 在这里,我们提供了一个简单的流线化协议来产生LOF iPSC系列,通过将CRISPR载体与附加型重编程质粒同时引入成纤维细胞,规避了传统基因编辑和已建立的iPSC系的克隆的技术挑战。 我们的实验已经产生了常染色体基因中所有3种基因型的几乎偶数。 此外,我们提供了一个详细的方法来维护和iPSC克隆的96孔板的基因分型。

【背景】CRISPR / Cas9技术允许简单且特异地针对特定基因组位置进行基因编辑。将该技术与诱导性多能干细胞(iPSC)的疾病建模和再生医学潜力相结合将继续对生物医学研究产生前所未有的影响。然而,使CRISPR / Cas9系统适应iPSC已经提出了几个挑战。在细胞系中进行基因编辑的传统方法是用表达Cas9蛋白质的质粒和指导RNA(gRNA)转染细胞,然后产生单克隆并筛选所需的遗传改变。不幸的是,iPSC不适用于单细胞克隆。已经开发了几种补充媒介和克隆方法来克服这一困难,但仍然充满昂贵的设备(低氧培养箱),困难的技术步骤(FACS分选的单个iPSC的存活)或劳动密集型方案(亚克隆)(Forsyth ,2006; Miyaoka ...

[Abstract]  Transfection of primary T cells can be challenging. This protocol describes a method to transfect primary human naive CD4+ T cells with an AP-1 luciferase reporter using low-level activation by phytohemagglutinin (PHA) and electroporation, as published (Palin et al., 2013). This technique is a modification of one previously described by our group (Cron et al., 2013). Anyone wishing to transfect murine T cells should consult the publication by Cron et al., 2013. This technique may be adapted for other primary T cell types by optimizing the Neon ... [摘要]  原代T细胞的转染可能是具有挑战性的。 该方案描述了使用植物凝集素(PHA)和电穿孔的低水平激活,用AP-1荧光素酶报道子转染初级人初始CD4 + T细胞的方法,如公开的(Palin等人 。,2013)。 这种技术是先前由我们组描述的技术的修改(Cron等人,2013)。 任何希望转染鼠T细胞的人都应参考Cron等人2013年的出版物。该技术可以通过优化氖电穿孔条件来适应其它原代T细胞类型,如文中所述。 可以使用其他荧光素酶或GFP报道分子,并且将需要优化该特定报道分子的刺激条件。
