> Use Lipofectamine, 6-well format
> Plates:

  1. BD002 (3:1) Flp-in T-REx
  2. BD002 (4:1) Flp-in T-REx

BD002 (3:1) = 339 ng/μl BD002 (4:1) = 317 ng/μl PlpE = 192 ng/μl

> Add 16 μL (4x) Lipo to 1000 μL (4x) Opti-MEM --> R.T/ 5 min.
> Add DNA to 250 μL Opti-MEM
> Add 250 Lipo mix into each 250 DNA mix --> R.T./ 20 min.
> Add 500 μL complexes to each 3.5 mL well (4 ml med. total each); Grow cells at 37°C
> Refresh medium after 5 hours (ab-free)
> Grow for one/two days, then plate dilution cultures in selection medium (+hygro)


Polycomb-ATF negative control lines: colony plates
> For each line make 2 plates: ~1x105 and 5x104 cells
> 25 ml 1 μg/mL puro, 15 μg/mL blast, 200 μg/mL zeo
> Also make 6-well back-up plate for all transfections (~3x105 cells in selection medium)
