Purpose

  • Test original totoRNAseq protocol (using RNaseIII buffer for RnaseIII and addition of 5xRT buffer for PAP treatment) without heating to 65C to inactivate enzymes. RNaseIII inactivation by RNase inhibitor addition and PAP limitation by 3'dATP or dATP addition
  • Testing difference of Ambion PAP and Affymetrix PAP (note that Affymetrix PAP showed significant A tailing of TSO and was completely inhibited by 3'dATP)
  • Testing Affymetrix PAP in RnaseIII buffer/RT buffer versus Affymetrix buffer (5x stock: 100mM Tris-HCl, pH 7.0, 3.0mM MnCl2, 0.1mM EDTA, 1mM DTT, 500 μg/ml acetylated BSA, 50% glycerol) Note that the Affymetrix buffer does not have the high salts seen in other PAP buffers and may be more compatible with RNaseIII as well as RT
