RE: lacunae and canaliculi stain
Tartrazine (C.I.640) can often be substituted for picric acid as a yellow
collagen and cytoplasm stain.
Tartrazine is very safe: it is used to color several brands of shampoo under
the name F&DC yellow #5.

Subject: lacunae and canaliculi stain
Hello All!
I have a researcher here who would like a thionin and picric acid stain
for lacunae and canaliculi. I would really like to avoid the use of
saturated picric acid. Are there any other stains that anyone knows of that
stains the same or similar? Could you share your procedure with me? Thanks
a million!!
