DNase binds to and is inhibited by actin. See:
Lacks, et al., Deoxyribonuclease I in mammalian tissues. Specificity of
inhibition by actin. 
       J Biol Chem. 1981 Mar 25;256(6):2644-8. 
Ulmer, et al., Engineering actin-resistant human DNase I for treatment of
cystic fibrosis. 
       Proc Natl Acad Sci U S A. 1996 Aug 6;93(16):8225-9. 

I don't know whether this inhibition would be complete enough for your purposes.
