Any hematoxylin powder without any other dye like Orange G (OG). The
hematoxylin Color Index is 75290, not 175290. Fisher, Polyscience, and Sigma
sell it, to name a few.

I have a couple of questions, though, if I could be so bold.
- how are you planning on disposing of the lead hematoxylin? It cannot be
disposed of down the sink, including all the water washing after hematoxylin
staining.
- have you consider immunohistochemistry for somatostatin? Much more
specific.

Subject: [Histonet] hematoxylins ??

Whats the best hematoxlyin powder/crystal to use in histology.  I purchased
a powder CI 175290 which contains OG powder ???.  In making up weigerts Iron
Hematoxylin I ended up using twice the recommended just to get the solution
to stain properly.  I will be making up a lead hematoxylin for pancreatic D
cells and am starting to think I need a different hematoxylin.
