Efficiency of Ampligase in situ Test

  • General idea: Will use Exo I & Exo III OR Exo III only to digest non-ligased padlock probes, then use dcProbe2RevComp to hybridize to padlock probe and detect
    • Exo III only because it's possible Exo I will degrade all rolonies, leaving the padlock probe (even after ligation) nothing to attach to so it'll be washed away and not detected
  • Ligation with Ampligase should protect the padlock probes from digestion, hence comparing wells +Exo with those -Exo will show what percentage of padlock probes are ligated

Hybridize 1uM ppMALAT1

  • Add 50ul 1uM ppMALAT1 for 20hr @45C in 1X Ampligase buffer +/- 0.5U/ul Ampligase

F3-F6: -Ampligase

Component Volume
10X Ampligase Buffer 20
100uM ppMALAT1 2
H2O 178
Total 200

F7-F10: + Ampligase

Component Volume
10X Ampligase Buffer 20
100uM ppMALAT1 2
5 U/ul Ampligase 20
H2O 158
Total 200
