02/20/10 ✓ RNA/ cDNA prep: 4-day dox Pc-ATF cultures (plate set A) ✓ Pc-ATF RT-PCR cultures: split plate set B into two duplicates; start new plate for KAH130-2 Cytology: seed 24-well cover slip plate for H3K27me/ H3K9me staining Very sparse cell growth. Do over on Tuesday ✓ Cultures: Split confluent Pc-ATF lines 1:10 (10 cm plates) RNA Preps/ cDNA synth. > RNA Preps --> Use 1 mL TriZol/ well (6-well dishes) --> Resuspend RNA pellet in 10 μL THE RNA Storage Solution Sample OD 260 260/280 ng/μL Vol. to use for cDNA synth. 1.
