Running Real-time MDA in PCR tubes to test different MDA conditions

  • Use both PGP1 cells and genomic human DNA
  1. 1ul 400mM ALS was added to 100 cells in 1ul PBS. Incubated for 1min in room temp.
  2. 1ul 400mM NS was added. Incubated for 1min in room temp.
  3. Added 1ul of (i) water (no protease) or (ii) 24mM protease and incubate at 40C or 50C for 15min
  4. Added 1ul of 250mM KOH (final 50mM) or 100mM KOH (final 20mM)
  5. Added 5ul of 50mM HCl or 20mM HCl (according to the previous step). Also added 5.5ul HCl (10% extra) and 6ul HCl (20% extra) to the test.
  6. Took 1ul out of the 10ul from above (equivalent to 10 cells) and added to 40ul MDA mix with SYBR Green.

Summary of Different Conditions

  1. DNA: 10 cells or 60pg human genomic DNA
  2. Cell lysis and DNA denaturation were identical in all cases.
  3. Neutralization: identical in all cases.
  4. Protease: (i) absent (ii) 40C 15min or (iii) 50C 15min
  5. DNA denaturation: final 50mM KOH or final 20mM KOH
  6. Neutralization: (i) HCl equal molar to KOH, (ii) 10% more HCl or (iii) 20% more HCl
  7. MDA: all identical conditions
