solubilizing nuclei

Hi all. 

I've got dishes in the freezer where I had treated cell layers with 
triton-x-100 for solubilizing plasma membranes and cytosol. 
Now the nuclei are frozen down there and I'm interested in measuring 
nuclear enzyme activity (WHAT a *nuclear* energy power this will 
unleash!!! ;-) So, SDS will be too heavy for that purpose (of course 
good enough for going onto a PAGE gel with them).
What do you suggest instead of scraping them off and sonicate 
(SONYcate ?? - using my walkman?? - uuh sorry, that's the sunday lab 
blues) them?

Any input is welcome!
