Several thoughts:

Why stain for so long? Try shortening the time to even a few minutes.
The yellow is probably leaching out in the acid water rinse. Try rinsing
in ethanol before clearing and mounting.

Subject: [Histonet] question about sirius red stain

Hi, All,

I stain collagen of frozen muscle section using regular sirius red
staining protocol(0.5g sirius red F3B in 500ml saturated picric acid,
section were stained 1h in solution, then wash in 0.5% acidified water
shortly). The background of images was all red under ordinary
microscopy, but not yellow as expected, collagen can be seen barely with
dark red. I extended washing time in acidified water, but no improvement
was gotten. I just wonder any one had similar experience and how to
improve it?

Thanks in advance.
