Are IDT oligos DNase- and RNase-free?

All of the custom DNA and RNA oligonucleotides that IDT offers are synthesized chemically, not enzymatically. As a result, there should not be DNase or RNase present in our samples. It is worth noting that there are abundant nucleases present in most environments, so good laboratory practice is very important to minimize potential exposure.
