what is RNase free HPLC?

This type of purification method is used for isolating RNA oligos, RNAase-free HPLC purification also extended to DNA oligos for use when there is a high sensitivity to ribonucleases. Rnase-free HPLC purification is carefully performed in an RNase-free environment; reagents, equipments/apparatus are monitored for RNase contamination. Guaranteed yields for purified, unmodified oligos 20 to 50 bases in length. Purity and yield guarantees may vary due to oligo length, modifications, or sequence composition.
