histone extraction

I’m looking for a histone extraction protocol for c.elegans.
I mashed up the worms and then used a classic protocol for mammal cells but it didn’t really work, the efficiency is very low.
any ideas???
thanks in advance

Have you tried the protocol in Ooi, Priess, and Henikoff?

I’ve found that also yesterday. seems to be workable…The only thing is I don’t have access to the articles they refer to so the protocol is not very clear, but I’ll try!
have you test it???
Thanks indeed
