Phenol /chloroform extraction is an easy way to remove proteins from your nucleic acid samples and can be carried out in a manner that is very close to quantitative.t is typically easiest to carry the extraction out in 1.7â2 mL eppendorf tubes. 1  Dilute your nucleic acid sample to 100â700 ÂµL or divide your samples into tubes such that you have no more than 700 ÂµL per tube. 2  It is difficult to do the extraction with volumes smaller than 100 ÂµL.
