  • cDNA synthesis: K562 sets 4 - 9



cDNA synthesis: K562

  • Use Carly's RNA from -80 °C
  • K562 1 and 3 are +PcTF and K562 2 and 4 are controls (see 12/18/12 ...will confirm when QC plate for mCh RT-PCR is run)
  • Will hold off on continuing U2OS for transiently transfected samples; will switch to KAH126 for further analyses


Measure RNA concentration

Sample OD 260 260/280 ng/μL Vol. to use for cDNA synth.
1. K562 1.1 -0.006 1.968 -5.193 n/a
2. K562 2.1 -0.003 1.6 -2.724 n/a
  • Conclusion: discard samples
  • Do a new RNA extraction from TRIzol samples


New RNA extraction

  • Follow the TRIzol/ RNeasy protocol
  • Use Carly's TRIzol samples K562 1, 2, 3, and 4


Measure RNA concentration

Sample OD 260 260/280 ng/μL Vol. to use for cDNA synth.
1. K562 1 0.975 2.017 780.25 3.2 μL (2.5 μg)
2. K562 2 0.890 2.021 711.81 3.5 μL (2.5 μg)
2. K562 3 0.856 2.028 684.53 3.7 μL (2.5 μg)
2. K562 4 0.696 2.020 556.52 4.5 μL (2.5 μg)
  • Conclusion: Success! Yields are very good. Continue with cDNA synthesis, 3 reactions per RNA.
