[Histonet] Congo red

[Cheri Miller]

Anyone have any solution to a week Congo Red? I use Rowley  Congo red, 1% aqueous order # S0-496. our procedure is Benholds and I cut at 5-6 microns. And I leave in the solution for up to 4 hours and the paths are still saying it is weak. Any ideas? I have even stopped the Alkaline alcohol differentiation step and its still too weak.
