I have used Dako's proteinase K for quite a few antibodies on FFPE
decalcifed bone sections.  The diluent of the Dako reagent is listed on
the spec sheet its 0.05mol/L Tris-HCL, 0.015mol/L sodium azide, pH 7.5.

Depending upon the antibody, I use the proteinase K for 2 to 5 minutes.

Subject: [Histonet] Proteinase K

Hello, all,
I plan to use proteinase k from Dakocytomation for antigen retrieval in
bone paraffin sections, but the specification only shows proteolytic
enzyme solution diluted in 0.05 mol/L Tris-Hcl, not the concentrations
in details, so I have no ideas, if you have some experience about it, I
hope you can do me a favor!Thank you!
