Abstract
The present invention relates to a process which comprises recovering proteinaceous materials from nucleoprotein complexes by derivatizing the proteinaceous material with a cyclic anhydride, thereby disassocating the complex, separating the derivatized proteinaceous material from the nucleic acids and subsequently regenerating the proteinaceous material. The recovery of the proteinaceous material is accomplished by maintaining the separated derivatized proteinaceous material at a suitable acidic pH, which is a function of the reaction time and the temperature, until the derivatized proteinaceous material is disassociated into the proteinaceous material and the cyclic anhydride or most usually the equivalent acid and the proteinaceous material is recovered.
