Day 1 - HEK replate Re-seed HEK cells to obtain 10-20% confluence (ideally early in the morning) After HEK adhesion (late afternoon) proceed with transfection using either Fugene or Lipofectamine 3000 Day 1A - Transfection by Fugene Confirm plasmids concentration and prepare the mix of packaging plasmids plasmid #9: 1750ng plasmid #10: 3240ng plasmid of interest: 5000ng. Equlibrate Optimem to RT Vortex and spin down Fugene Dilute plasmid mix in 1mL Optimem, vortex, spin down Add 30uL of Fugene, mix by inverstion incubate 5-15minutes at RT Apply dropwise to 10cm dish Incubate overnight Day 1B - Transfection by Lipofectamine Confirm plasmids concentration and prepare the mix of packaging plasmids plasmid #9: 1750ng plasmid #10: 3240ng plasmid of interest: 5000ng. Equlibrate Optimem and Lipofectamine components to RT Vortex and spin down components Solution A: Dilute 35uL of Lipofectamine in 875uL of Optimem, vortex, spin Solution B: Dilute 20uL of P3000 from Lipofect kit in 875uL of Optimem, add your plasmids, mix by pipetting Mix A and B, incubate 10-15 min at RT Apply dropwise to 10cm dish Incubate overnight Day 2 - Exchange media Change media to 10 %KOSR in DMEM high Glucose (15mL)
