服务介绍 毕赤酵母是一种非致病性、专性好氧的单倍体芽殖酵母,是目前分子生物学领域最杰出的“蛋白生产工厂”之一。它是一种能够以甲醇为唯一碳源和能源的甲基营养型酵母。普因特生物以CRISPR/Cas9系统为代表的第三代编辑技术,凭借其高效性和简便性可对毕赤酵母基因组进行定点修饰,包括敲除特定基因、敲入外源序列、引入点突变等,以实现菌株功能优化和代谢通路重构。 服务优势 ▶经验丰富:在毕赤酵母基因编辑领域有丰富的经验积累,经验丰富的团队可以帮助您快速完成毕赤酵母突变体构建; ▶质量保证:确保所有基因编辑位点都经过测序鉴定,以确保产品质量。 服务流程
文案展示 Combinatorial optimization of CRISPR/Cas9 expression enables precision genome engineering in the methylotrophic yeast Pichia pastoris 期刊:Accepted Manuscript
(B) Cells were transformed with plasmids (based on design #82, Tab. 1) bearing HsCAS9, GUT1-gRNA2 and a gRNA to target AOX1 (gRNA1, gRNA2 or gRNA3) and stamped onto BMD1, BMM1 and glycerol (BMG1) containing agar plates Depending on the gRNA combination used multiplexing efficiencies up to 69% were obtained. Mean values and standard deviations of biological triplicates are shown.(C) Representative experimental data of the phenotypic characterization of the experiments in (B) are shown (CRISPR/Cas9 plasmid bearing the gRNAs AOX1-gRNA2 and GUT1-gRNA2). As controls the P. pastoris wildtype strain (WT), mutS (ΔAOX1) and a ΔGUT1 strain were used . 适用领域 ▶代谢工程与化合物合成:能高效合成各类高价值化合物,甚至完成复杂的多基因编辑以重构代谢通路。 ▶蛋白表达与医药工业:能更好地解决宿主自身的局限性,提升产量与产物质量。 ▶菌株功能优化:除了直接生产产物,基因编辑也常被用来系统性地改善毕赤酵母“底盘”细胞自身的各项性能。 ▶基础科学研究:通过编辑特定基因,可以探究其功能,解析毕赤酵母的生长、代谢和应激响应等生命机制。 上一篇解脂耶氏酵母基因编辑下一篇葡萄球菌基因编辑 |
