The Double Nickase Plasmid features a U6 promoter for sgRNA expression, a 20 nt targeting sequence, and a gRNA scaffold to guide Cas9n. It includes a CBh promoter for Cas9n (D10A) and puromycin resistance, GFP for transfection verification, and nuclear localization signals (NLS). The 2A peptide allows co-expression of Cas9n and Puro from a single promoter, enabling precise genome editing with reduced off-target effects.

Cas9n Nickase gRNA Plasmid Targeting: Dual gRNA plasmids create single-strand nicks at precise DNA sequences for efficient genome editing using Cas9n Nickase.

This image illustrates the Cas9n Nickase mechanism used for precise genome editing. Two plasmids (Plasmid 1 and Plasmid 2) are shown, each containing a targeted DNA sequence. The system utilizes single-guide RNAs (sgRNA) to direct Cas9n Nickase to specific genomic locations, represented by the blue and pink DNA strands. The sgRNA scaffold aids in guiding Cas9n to the 20 nucleotide (nt) target sequence on the DNA. Cas9n makes single-strand cuts at NCC and NGG sites, enabling precise gene modifications without creating double-strand breaks.

    TNFRSF1A 编码 TNF-R1，这是一种广泛表达的受体，可与 TNF-α 结合并启动信号转导，从而调控炎症、细胞存活以及程序性细胞死亡。配体结合会促进受体相关复合物的组装，这些复合物可激活经典的 NF-κB 和 MAPK 通路，诱导细胞因子及应激反应相关的基因表达程序；在特定调控背景下，也可能转向以半胱天冬酶依赖的凋亡和程序性坏死（necroptosis）为主的途径。通过这些通路分叉，TNF-R1 影响先天免疫激活、组织稳态，以及内皮与上皮屏障反应。TNFRSF1A 信号异常以及影响受体功能的变异与自身炎症表型及更广泛的炎症性疾病机制相关，因此常被用作解析 TNF 驱动网络行为的研究靶点。

    TNF-R1 双切酶质粒（h）由一对匹配的质粒组成，专为在 human 细胞系中对 TNFRSF1A 位点进行高特异性编辑而设计。每个质粒分别表达Cas9 D10A切口酶和针对TNFRSF1A内不同DNA链的独特sgRNA。当这两种切口酶被引导至相邻但位于DNA链相反侧的位点时，会产生错位的单链切口，从而共同形成错位双链断裂，这需要两个引导RNA在靶位点上协同发挥作用。由此产生的DNA断裂通过内源性细胞修复途径（最常见的是非同源末端连接（NHEJ））得到修复，从而导致插入或缺失，进而破坏TNFRSF1A的功能。通过要求双sgRNA在靶位点结合，双切口方法提高了编辑特异性，并为需要对靶向精度进行额外控制的应用提供了互补的CRISPR策略。

    为高效识别编辑后的细胞，其中一个质粒编码GFP以实现转染细胞群的荧光可视化，而配套质粒则携带嘌呤霉素抗性基因用于抗生素筛选。这些特性共同支持共转染细胞群的高效富集，并简化了TNFRSF1A基因失活克隆的验证流程。

    仅供研究使用。不用于诊断或治疗。
