By nuclear extracts do you mean just the DNA (in which case a simple
precipitation method should work) or the whole nucleus including the
membrane and any proteins there - which is a bit more tricky?
WRT markers, LDH is about as good a cytosolic marker as any - rock solid
spectrophotometric rates and lots of kits available from Sigma e.t.c. if
you can't be bothered to work up a method. Mitochondrial markers are a bit
more tricky - try citrate synthase (a matrix enzyme), as its easy to
assay. However your contamination might be from the mito' membrane
fraction, so try monoamine oxidase (outer membrane) or cytochrome c oxidase
