Smart-Seq2 Procedure step3 | Modification | Reason |
---|---|---|
9: Reverse transcription | TSO, oligo-dT and ISPCR oligos have a 5′ biotin modification | Reduces concatamer formation and increases gene mapping percentage for sequence reads |
14: cDNA PCR thermal cycling | Increase the number of amplification cycles from 18 to 21 | To compensate for the lower amount of RNA in a nucleus compared with a whole cell |
