Figures and Data

High Functional Titers with TransIT-Lenti Transfection Reagent

High Functional Titers with TransIT®-Lenti Transfection Reagent. Adherent 293T/17 cells were transfected in a 6-well plate with pLKO.1-puro-CMV-TurboGFP™ transfer vector and the Lentivirus Packaging Mix powered by MISSION® (1:1 ratio, 2 µg/well) with the following reagents: TransIT®-Lenti (3:1, vol:wt), Lipofectamine® 2000 (3:1), Lipofectamine® 3000 (3:1:1), 25 kDa PEI (6:1), or CaPO4 precipitation (4 µg pDNA/well). The supernatant was harvested, filtered (0.45 µm), and titered using 293T/17 cells. Lentivirus transductions were performed in the presence of 8 µg/ml TransduceIT™ and GFP expression was measured 72 hours post-transduction using guava easyCyte™ 5HT Flow Cytometer. Error bars represent triplicate transfection complexes titered individually. Functional titers were calculated using virus dilutions with less than 20% GFP positive cells.

High Transduction Efficiency in Neuron Cells with Unconcentrated Lentivirus Using TransIT-Lenti

High Transduction Efficiency with Unconcentrated Lentivirus Using TransIT®-Lenti. (A) Lentivirus was produced with the TransIT®-Lenti Transfection Reagent (3:1, vol:wt) or Lipofectamine® 2000 using the MISSION® vectors (pLKO.1-puro-CMV-TurboGFP™ transfer vector and the Lentivirus Packaging Mix powered by MISSION®). The supernatant was harvested, filtered (0.45 µm), and frozen. Lentivirus transductions were performed 5 days post-plating with iCell® Motor Neurons (Cellular Dynamics International). For bothTransIT-Lenti and Lipofectamine® 2000, one microliter of unconcentrated supernatant was added per well of a 96-well plate. GFP efficiency was measured 72 hours post-transduction using guava easyCyte™ 5HT Flow Cytometer. Error bars represent the SEM of duplicate wells. (B) iCell® Motor Neurons were plated in Ibidy 35mm dishes and transduced withlentivirus produced using the TransIT®-Lenti Transfection Reagent and MISSION® vectors. Images were captured at 72 hours post-transduction with a Zeiss Axiovert S100 inverted fluorescence microscope using a 63X objective under oil.

Functionality Comparison of CaPO4, Lipofectamine 2000 or TransIT-Lenti Generated Lentivirus.

Comparison of CaPO4, Lipofectamine® 2000 or TransIT®-Lenti Generated Lentivirus.  HIV CMVeGFP Virus was produced in HEK 293FT cells using either CaPO4, Lipofectamine® 2000 or TransIT®-Lenti Transfection Reagent per the manufacturer’s protocol. Lentivirus was collected 48 hours post-transfection and concentrated by prolonged centrifugation at 9,000 x g. HT1080 cells were infected with a 1:100 or 1:1000 dilution of each concentrated lentivirus. Images (above) were captured 48 hours post-transduction.
