包病毒(预实验)

2024.12.24 293T传到2个10cm dish(每dish 6Million细胞)

2024.12.25 24h后约30~40% confluency. 换液到10mL DMEM,分别用vigofect和neofect转染 P2 4xBrunello human lentivirus sgRNA (Cas9 DR) library plasmid.

Vigofect: 150mM NaCl (0.22μM 过滤除菌)稀释。Tube1: 9μg P2 + 3μg PMD2G + 6μg PSAX2,NaCl补全到450μL;Tube2: 7.2μL vigofect + 442.8μL NaCl;两tube混匀,室温15min. 加入细胞培养物.

Neofect: Opti-MEM 稀释。In one tube: 9μg P2 + 3μg PMD2G + 6μg PSAX2,用Opti-MEM稀释混匀,加入18μL (质粒μg数:Neofect体积=1:1)Neofect,混匀(终体积500μL),室温15min. 加入细胞培养物.

2024.12.25 23:30转染.
