Hi Histonetters

I posted this question last week, but I got no response, so I will try
again in hope of some.

Does anyone have a protocol for Van Gieson staining on frozen sections.
Alternatives to this staining method for collagen are also welcome as long
as they work on frozen sections. I need it for a 3D in vitro skin model
growing in a matrix that cannot be formalin fixed and paraffin embedded.
