Third Try: in tube SplintR Test with formamide and ET SSB
- First try showed SplintR with 10% formamide had the best sensitivity and specificity of the conditions tried
- Second try had unexpected trend with increasing formamide led to increased sensitivity
- Third try confirmed second try
- Try with 95C 3min denature before hybridization
Test Conditions
- Standard: SplintR only
- SplintR + 5% formamide
- SplintR + 7.5% formamide
- SplintR + 10% formamide
- SplintR + 12.5% formamide
- SplintR + 15% formamide
- SplintR + 17.5% formamide
- 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
- one sample with ALL padlock probes and template
Padlock Probes and Template
- ppCUX2
- ppBCL11B
- ppRELN_1
- ppGFAP
- ppMALAT1
- /5Phos/TTTCTGCCTTTACTTATCAATTCCTTCAGCTTCCCGATATCCGACGGTCTACTTCGTCGCGTCAGACCAAATGGAGGTATGACATATAATCT
- Template for ppMALAT1: MALAT1_template
- /5AmMC6/GAATTGATAAGTAAAGGCAGAAA AGATTATATGTCATACCTCCAT

8 | Ampligase | 4.5 or 5.4 (0.9ul of each 1uM oligo) | 3 | 0 | 25.2 or 22.5 (these were added before realizing wrong volume. Kept as is) | 30 |
- Combine padlock probes and template in 1X Ligase buffer and possibly formamide
- Add mineral oil on top
- Incubate at 95C for 3min
- Incubate at 55C for 18hr
