Guaranteed Yield
Yield will vary based upon base composition, purification, oligo length, scale and modifications. That's why we have set minimum yield standards - guaranteed quantity. However, it is typical that you may receive more than the minimum yield guarantee. See our Yield Chart for details.

Guaranteed Quality
Oligos are routinely checked for length, purity, and composition. Our global quality control capabilities include MALDI-TOF mass spectrometry, electrospray ionization mass spectrometry (ESI-MS), capillary electrophoresis (CE), and polyacrylamide gel electrophoresis (PAGE). If you are dissatisfied and report an oligo problem within 30 days of order receipt, we will gladly remake your oligo free of charge or provide a credit for the purchase amount.

All orders are shipped with a Quality Assurance document that includes measured yields, melting temperature, MW and µg/OD with every oligo. Oligos in tubes are accompanied by an extra vial label for your records.
