Yes, it should work

Bryan Douglas Crawford

I've always used home-made hybjuice but I can't imagine why commercial products wouldn't work. I would suggest you do at least one 50/50 incubation with whatever buffers you're using before and after the hybridization steps so you're not slamming your tissues from one solvent condition to another. Good luck!
