I would like to know your opinion on kits for separation of nuclear and cytoplasmic fraction. I have used NE-PER™ Nuclear and Cytoplasmic Extraction Reagents, but I was not satisfy with the results even though I did some optimizations. Now I'm planning to order Cell Fractionation Kit #9038 and I need some helpful information if I made a good chose. I'm open for any suggestions. Thank you in advance!
