- ✓ U2OS Flp-in T-REx: add dox to Dox+ wells (6-well plate from 2/08)
- ✓ Transfection: Gal4-EED constructs in HEK293 luc reporter line
- ✓ Polycomb-ATF lines: frozen stocks for 90% confluent plates: 127-4, 128-8, 132-8; 1x 1:10 plate (per line)
Transfection
> HEK293 cells + Gal4-EED constructs (KAH139, 140, 141/V0201)
> Use Fugene, 24-well format
> Serial dilutions of plasmids: 800 - 25 ng in 5 μL
--> Start with 1600 ng in 10 μL OptiMEM
