Hi. I want to do (renal) denervation to mice. So, I searched for some protocols and those said: "use 10% phenol". But I don't know what I have to use exactly.

Do I have to use powder phenol for Sigma or liquid phenol?

What do you use 10% phenol when you do denervation to mice or rats?

Please tell me about how to make "10% phenol".

Thank you :)
