Abstract
A method of making full-length oligonucleotide arrays provides for the purification of pre-synthesized full-length oligonucleotides from shorter length oligonucleotides and other impurities at the same time the oligonucleotides are deposited on the array. A synthesized mixture that includes desired full-length oligonucleotides and some capped shorter length or 'failed' oligonucleotide sequences, is reacted with a linking agent to add a linking group on to the free-end of the full-length oligonucleotides but not the shorter-length oligonucleotides. The resulting mixture is deposited on an array without first separately purifying the mixture to remove the unwanted shorter-length oligonucleotides. After deposition, unbound material, including the shorter length oligonucleotide sequences and other impurities, is removed.
