How to inactivate proteins in organ extracts?

Dear Experts!

How to inactivate proteins in an aqueous organ extract? An attempt to
digest them with trypsin failed, probably due to trypsin inhibitor from
blood / serum present in the samples. Heating / boiling comes into my
mind, but this might kill other unknown substances in the extract.

I would like to tell if a certain effect of this extract is due to a
protein or something else.

Any ideas?

Thanks for your input!
