ABSTRACT:
Crude nucleic acid solutions can be selectively separated using a membrane separating process, it being possible for the high molecular weight DNA to be isolated from the retentate and the low molecular weight RNA to be isolated from the permeate. Ultrafiltration on hollow fiber membranes is preferred.
