Protocol
- Circularization (all samples)
- Heat inactivate enzyme by incubating for 2 minutes at 94C
- Exonuclease Digestion
- Prepare exonuclease I/III mix by mixing 30 uL exonuclease I (20 units/μL) and 6 uL exonuclease III (100 units/μL) in 1:1 ratio
- Add 2 μL of exonuclease I/III mix to reaction
- Mix the reaction by swirling pipette around the well 5 times
- Incubate reaction at 37 ºC for 2 hours
- Heat inactivate enzyme by incubating at 94C for 5 minutes
- Rolling Circle Amplification (Samples 1,3,5,7)
- Prepare samples in new tube according to following table
- qPCR
