I understand you're doing a phenol extraction; you can increase the
volume of the organic phase added... you can just spin harder or longer...
or do one or more rounds of extraction...
On the other hand, if possible, just redesign primers so that
contamination doesn't hamper interpretation...
Several ways to skin the cat here...
