Abstract

The invention is directed to methods for synthesizing a plurality of oligonucleotides in the same reaction vessel, and in some embodiments, using the synthesized oligonucleotides in an oligonucleotide-based assay in such reaction vessel. In some embodiments, methods of the invention are implemented by steps of (a) providing a plurality of different initiators attached to one or more supports, each different initiator having a terminal nucleotide with a different 3-O-blocking group; (b) for each different initiator, synthesizing a polynucleotide by repeated cycles of template-free enzymatic additions of 3′-O-blocked nucleoside triphosphates, wherein the blocking group of the 3-O-blocked nucleoside triphosphate is removable under deblocking conditions orthogonal to the deblocking conditions for removing blocking groups of the other initiators; and (c) releasing the oligonucleotides from the polynucleotides and the one or more solid supports.
