Purpose
- Test PAP Activity from different companies:
- Ambion
- Enzymatics (used up to this point)
- Affymetrix
- Test Blocking of PAP activity using Cordycepin-ATP

- Affymetrix PAP (60U)with 3'dATP
- 1mM ATP/0mM 3'ATP
- 1mM ATP/0.01mM 3'ATP
- 1mM ATP/0.05mM 3'ATP
- 1mM ATP/0.1mM 3'ATP
- 1mM ATP/0.5mM 3'ATP
- 0mM ATP/1mM 3'ATP

Adaptation to totoRNAseq
- totoRNAseq Reaction Buffer
- Test:
- Ambion PAP vs Enzymatics PAP in RT/RNaseIII buffer
- Commercial mix (see above)
- totoRNAseq mix with 1mM ATP
- totoRNAseq mix with 10mM ATP
- Commercial mix pre-heat inactivated
- Ambion PAP vs Enzymatics PAP in RT/RNaseIII buffer
