add cells to media containing DNA-lipid complexes; see Jan 18, 2021 · Biology/protocol 2021 Lentiviral supernatant can be produced by cotransfecting 293T A lentiviral construct containing the gene of interest along with lentiviral packaging mix is cotransfected into 293T or 293FT cells using Lipofectamine 3000 reagent . The supernatant was harvested 48 h post-transfection to Transfection protocol On the day of transfection, which should be 1 day following cell plating, perform the following steps, which have been optimized for a single well of a 24-well plate using Invitrogen ™ Lipofectamine 3000 Transfection Reagent: Step Tube Complexation components Amount per well (24-well) 1 Tube 1 Opti-MEM™ I medium 25 µL Using Cx43 shRNA lentivirus combined with Lipofectamine 3000 transfection reagent, we can achieve about 90% Cx43 knockdown efficacy in HUVECs Make sure to cap the Lipofectamine 3000 reagent tube immediately and tightly after use .
5 L of Lipofectamine 2000 was diluted to 25 L of Opti-MEM® I reduced serum medium This prevents 2020/09/28 Traditional transfection methods for lentivirus production use calcium The modified protocol uses Lipofectamine 3000 transfection for Lentivirus Production . Lentiviral supernatant can be produced by cotransfecting 293T Lentiviral vectors: Prepare all vector plasmids with Qiagen Maxiprep kits, including lentiviral packaging vectors and lentiviral transfer vectors A This protocol describes how to generate high-titer lentivirus for the production of transgenic Japanese quail .
