The template-switch reaction was conducted following the procedure previously described [43] .
Additionally, to enhance the efficiency of this reaction, we incorporated polyethylene glycol (PEG 8000; Promega) at a concentration of 10% w/v in each reaction, as previously mentioned. This inclusion of polyethylene glycol aids in promoting optimal reaction conditions acting as a molecular crowding agent and thereby facilitates the successful transformation of ssDNA into dsDNA.
