why is my histone h3 more in the cytosol than the nucleus?

I am doing cyto/nuc fractionation, when I use Histone h3 (Santa Cruz, sc-10809) as nuclear marker, I always found it's more in the cytosol than the nucleus. I use low salt/high salt protocol to get my fractions, and besides H3 I also probe PARP1, which is mostly in the nucleus, what gives? thanks!

do you mean that there are lots of cytoplasm protein in the nuclear extract if I am using a low /high salt method?
