I wanted isolate separately cytoplasmic and nuclear proteins from
cells. These are human primary effusion lymphomas cells, which are
suspension cell cultures and latently infected by HHV8 (KSHV).The
specific problem is that my cytoplasmic extract is always contaminated
by proteins from nuclei fraction.(has been checked by cytosolic and
nuclear markers, by Western)
I tried many, many different options i.e hypotonic buffers, various
detergent and many variants of salt concetration....
