GeneWorks Oligos


Welcome to GeneWorks’ Custom DNA Oligonucleotide service.

GeneWorks offers Australian and New Zealand scientists a fast, economical and quality-guaranteed service backed by the highest level of customer support. Oligo synthesis began in our Adelaide laboratories in 1986, and we remain the only commercial supplier to make all its oligos in Australia. In December 2005, GeneWorks achieved ISO 9001 accreditation for its Australian operation, including the Quality systems used in the Custom Oligo Synthesis and Quality Control laboratories.

  • Oligos with ‘N’ at the 3' end
  • Oligos with modifications/labels at the 3' end
  • Dual labelled probes
  • Phosphorothioate (S) oligos including mixed linkages
  • Expanded range of internal, 5' and 3' modifications
  • Bulk discount for 5' amino labeled 40 nmole scale oligos
  • Short oligos (≥5 bases)
  • Long oligos (≤110 bases)
