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.

One pot synthesis of sets of oligonucleotides

The invention is directed to methods for massively parallel template-free enzymatic synthesis of a plurality of different polynucleotides of predetermined sequences. In one aspect, methods of the invention employ large scale arrays of reaction sites each associated with at least one working electrode for controlling deprotection and deblocking steps at predetermined user selected sites. In another aspect, the invention provides template-free enzymatic synthesis with proofreading, wherein completed polynucleotides at predetermined reaction sites are sequenced using a sequencing by synthesis technique, particularly employing electrochemically labile blocking groups.

Massively parallel enzymatic synthesis of nucleic acid strands

The invention is directed to systems, apparatus and kits for automated synthesis of a plurality of polynucleotides in an array of reaction chambers using a template-free polymerase. In some embodiments, adaptive elements and processes are provided to monitor and control disruption of the synthesis process and fluid movement by enzyme aggregation.
