WebA practical strategy for the total stepwise solid-phase synthesis of peptide-oligonucleotide conjugates was developed. In this strategy, the Boc/tBu protecting groups are utilized for the side chains of Trp, His, Arg, Asp, and Glu, and is deprotected in borate buffer at 90 °C to avoid depurination of the oligonucleotide caused by strong acid treatment. WebThe protected L-tyrosine segment was preferred in order to avoid possible side reactions during the polymerization procedure due to the hydroxyl (-OH) groups in the monomeric unit of the peptide. Size exclusion chromatography (SEC) was used in order to calculate the total number average molecular weight of each segment, as well as the dispersity indices of all …
