FAQ: Is the Template Switching RT Enzyme Mix compatible with RT primers with degenerate bases for cDNA synthesis and amplification, as described in the mcSCRB method [1]? 

We have compared the performance of the Template Switching RT Enzyme Mix and Maxima H Minus Reverse Transcriptase (Thermo Fisher Scientific). The cDNA libraries made with the NEB Template Switching RT Enzyme Mix contain at least 10% more transcripts than those made with Maxima H Minus supplemented with 7.5% PEG as described in the mcSCRB method. In addition, the NEB libraries exhibited improved RNA base distribution metrics as listed below:
