Day 1 (today)
> Add Lipo to 250 μL Opti-MEM --> R.T/ 5 min.
> Add DNA to 250 μL Opti-MEM
> Add DNA mix to Lipo mix --> R.T./ 20 min.
> Remove 0.5 mL growth medium from each well before adding transf. mix. Add 500 μL complexes to each well (total vol./well = 4 mL); Grow cells at 37°C
> After 5 hours, change medium (ab-free)
Day 2 (12/18/09)
> Transfection (DNA+Lipo) was slightly toxic, no need to split cells; change medium to 15μg/mL puro(morning)
> Do microscopy to find RFP+ cells (record positions using Metamorph multi-position staging)
> Add 1 μg/mL doxycycline
Day 3
> Microscopy: record RFP vs. YFP expression at set stage positions
Day 4
> Repeat Day 3
