Red-book or maniatis contain a method for purifieing nuclei. The sup
containes the cytoplasmic RNA.
The method uses Tris, MgCl2, NP40. You add DTT, spermidine and RNAsine (a

centifugation is 500g 5' twice.
I don't remember the concentrations by heart though I made the solution
High grade nuc/cyto RNA is achieved from many different tissues and cell
