Second Try: in tube SplintR Test with formamide and ET SSB

Test Conditions

  1. Standard: SplintR only
  2. SplintR + 5% formamide
  3. SplintR + 7.5% formamide
  4. SplintR + 10% formamide
  5. SplintR + 12.5% formamide
  6. SplintR + 15% formamide
  7. SplintR + 10% formamide + 250ng ET SSB
  8. Positive Control: Ampligase
  • For each test conditions have
    • one sample with ALL padlock probes and template
      • Should see amplification
    • one sample with all padlock probes with NO MALAT1 template
      • Should not see amplification

Padlock Probes and Template

  • ppCUX2
  • ppBCL11B
  • ppRELN_1
  • ppGFAP
  • ppMALAT1
    • /5Phos/TTTCTGCCTTTACTTATCAATTCCTTCAGCTTCCCGATATCCGACGGTCTACTTCGTCGCGTCAGACCAAATGGAGGTATGACATATAATCT
  • Template for ppMALAT1: MALAT1_template
    • /5AmMC6/GAATTGATAAGTAAAGGCAGAAA AGATTATATGTCATACCTCCAT

5 SplintR + 12.5% formamide 1.5 or 1.8 (0.3ul of each 10nM oligo) 3 3.75 21.75 or 21.45 30
6 SplintR + 15% formamide 1.5 or 1.8 (0.3ul of each 10nM oligo) 3 4.5 21 or 20.7 30
7 SplintR + 10% formamide + ET SSB 1.5 or 1.8 (0.3ul of each 10nM oligo) 3 3 22.5 or 22.2 30
8 Ampligase 1.5 or 1.8 (0.3ul of each 10nM oligo) 3 0 25.5 or 25.2 30
  1. Combine padlock probes and template in 1X Ligase buffer and possibly formamide
  2. Add mineral oil on top
  3. Incubate at 55C for 17hr
