Hi all,
I have a couple of questions regarding decal and staining. I have done some searching but could use some hands on experiences.
It involves bone regrowth. The sample will vary in size. From my reading, it seems that 5% formic  or 10% EDTA is preferred. The researcher asked about acetic acid, but I have never heard as acetic alone as a decal, isn’t it just used to balance pH of the EDTA? It is my understanding that the decal step will be done somewhere else then the sample sent to me. That lab feels that HCL decal will not  not affect the sample. I think otherwise. The staining they have talked about is the Goldners Trichrome mainly. The researcher mentioned Safranin O but from my conversations I think they have little knowledge of histology and I work in a cardiovascular lab with my only experience has been with mouse tibia and these samples will be from a larger source.
Type 2 collagen was brought up but when I said that was an immuno stain they did not realize that.
Si in a nutshell, what decal sol. would be better and what stain?
Sorry for the rambling.
