Which oligo purification method would minimize contamination with environmental DNA?

Since all of our oligos are chemically synthesized (versus isolated from an organic source), our oligos should only contain the specific sequence you request (plus a small percentage of n-1mer internal or truncation products) and there should be no external DNA contamination. For oligos longer than 50 bases, we recommend either PAGE or IE-HPLC purification to reduce the amount of truncated and deletion products in the oligo.
