- 3 samples
- No additives
- 5% formamide
- 10% dimethylformamide
- 5% Gel mix with 1% crosslinker (normally 0.5%) and protocol is same as this with Acryloyl-X
Component | Volume |
40% AB 99:1 Mix | 6.25 |
10% BSA | 1 |
10mg/ml Acryloyl-X, SE in DMSO | 1 |
H2O | 39.75 |
5% TEMED | 1 |
5% APS | 1 |
Total | 50 |
Protocol[edit]
Day 1[edit]
- Prepare 3 plastic culture dish with 12x17mm hole, tweezers, large plastic dish, and 50C hot plate
- EtOH and UV sterilize
- Made 4% PFA in 1X PBS 2 weeks ago stored at RT
- 10ml 16% PFA + 4ml 10X PBS + 26ml H2O
- Take out brain section from -80C and dry on 50C hot plate for 3min
- Submerge coverslip in 5ml 4% PFA in petri dish for 15min at 37C
- Wash twice with cold 1X SSPE by submerging
- Add 0.25% TX-100 in 2XSSPE and incubate 10min at RT
- Wash with cold nf-H2O three times and check for degradation
- Skip pepsin step usually done here
- Aspirate any liquid and place a glass slide with 50um spacer over the coverslip with tissue
- Secure in plastic jig
- Add 50ul gel casting mix filtered and degassed
- Seal in plastic bag and vacuum out air before filling with argon
- Let sit at RT for 30min
- Aspirate non-polymerized gel and wash once with 1X PBS
- Attach coverslip to bottom of petri dish
- Aspirate non-polymerized gel and wash once with 1X PBS
Prepare Padlock Probes[edit]
- 1ul 10uM (50nM) each padlock probe
- ppCUX2 (dcProbe6-Cy3)
- /5Phos/TTCACCCTCTTGGTGATGGAGTAC CTTCAGCTTCCCGATATC TCGTAACCCGTGCGAAGTGC CTAGATTGTTGTCTGTGAGGACCTCC
- ppBCL11B (dcProbe6-488)
- /5Phos/AGCAGCTCAGTTTGCATTGCTT CTTCAGCTTCCCGATATC CACGCTTACGATCCCGCTAT TTGTTTCACAATTTCTCAAGGACTAA
- ppMALAT1 (dcProbe2-Cy3)
- /5Phos/TTTCTGCCTTTACTTATCAATTC CTTCAGCTTCCCGATATC CGACGGT CTACTTCGTCGCGTCAGACC AAATGGAGGTATGACATATAATCT
- ppCUX2 (dcProbe6-Cy3)

- 10ul (5%) formamide or 20ul (10%) DMF or 0ul
- 162ul H2O, 152ul H2O, or 172ul H2O
- Pre-heat to 95C and then add to dish
- Add 5ul 40U/ul (1U/ul) RNase Inhibitor
- Put at 60C in EZ oven and set to 55C to incubate overnight
- Forgot to set to 55C so did 60C overnight and then 4.5hrs at 55C
