How is my ZNA® QCed?

All ZNA® oligos are routinely analyzed by checking and verifying the molecular weight by Mass Check analysis (ESI- or MALDI-ToF) for actual molecular weight determination and comparing the result with to the theoretical and to be expected mass. If practice meets theory applying our strict quality criteria are the basis for final product release.

Mass Check analysis (ESI- or MALDI-ToF) is routinely performed on all ZNA®s. If the theoretical expected mass matches the molecular weight determined by the mass check, the product is released.
