[Histonet] Rhodanine Copper stain

[Carrie Disbrow]

Hello!
I wonder if anyone knows if copper pigments can be stained in 3 micron FFPE human liver core biopsies using a Rhodanine Copper staining method? The procedure suggests 6- 8 microns. Our small amount of  tissue core biopsies are cut at 3 microns and if possible we would not like to cut the block again.
Thanks for your input.
Thank you,
