PURIFICATION OF CELLULAR COMPONENTS THAT ARE SUBSTANTIALLY RNA FREE

摘要

The invention relates to host cells and methods of preparing a substantially RNA-free cellular component, comprising culturing cells producing the cellular component in a medium and lysing the cells to produce a cell lysate, wherein the cell lysate contains the cellular component and sufficient RNase activity to degrade substantially all of the RNA molecules present in the cell lysate. The invention also relates to substantially RNA-free cellular components.
