我们描述了一种光激活基因组编辑平台,该平台基于当暴露于生物相容性近红外光脉冲时从等离子体纳米颗粒载体释放酶。该平台依赖于铜存在下多组氨酸标签与次氮基三乙酸的强大亲和力,铜附着在金纳米颗粒表面自组装的双链核酸上。我们还采用包含 TAT 内化肽序列的 Cre 重组酶的蛋白融合来实现内体定位。使用商用双光子显微镜观察红色荧光报告基因的高分辨率基因敲入。据描述,高通量照射可产生有用数量的编辑细胞。
We describe a light activated genome editing platform based on the release of enzymes from a plasmonic nanoparticle carrier when exposed to bio-compatible near infrared light pulses. The platform relies on the robust affinity of polyhistidine tags to nitrilotriacetic acid in the presence of copper which is attached to double stranded nucleic acids self-assembled on the gold nanoparticle surface. We also employ a protein fusion of the Cre recombinase containing a TAT internalization peptide sequence to achieve endosomal localization. High resolution gene knock-in of a red fluorescent reporter is observed using a commercial two-photon microscope. High-throughput irradiation is described to generate useful quantities of edited cells.
