> Yes, it's easy to stain both cell-types. First stain with eosin at a high pH (such as 8) to obtain selective coloration of eosinophils. (Paneth cell granules will also stain if your tissue is intestine.) Wash in slightly acidified water, then stain with dilute toluidine blue at a low pH (less than 2 to be selective for mast cells, cartilage matrix and some types of mucus). The staining is metachromatic - purple to red, rather than blue, but not likely to be confused with the eosin colour. Rinse in slightly acidified water, dehydrate in 3 changes of 100% alcohol, clear in xylene and apply coverslip.
> Slightly acidified water = approx 0.5% acetic acid. Check with a microscope at both the washing stages to make sure the eosinophils and mast cells are adequately stained. As described above, nuclei should be unstained. If you want blue nuclei, use the toluidine blue at pH 3 to 4, being careful to avoid over-staining.

> If you use an FDA approved kit for the staining which not only costs much more than a routine 88342, but also requires more steps that may not fit into an IHC lab's routine protocol (since you cannot alter any step in the kit) calling for special handling and more labor, I can see justification in increased RVU for the technical component.  I currently use FDA approved kits for HercepTest & EGFR staining and I can say, without question, that the technical cost, in terms of both labor and reagents, is more than when I did these two IHC's before bringing in the kits.

This is in comparison to a matched tissue control in 10% NBF. My recipe requires fixation at 4C for 48 hours via 1 gram of periodic acid in 100 mls 10% NBF. Anyone else using this fixation method? Any suggestions or advice is greatly appreciated,> > Denise Bland-Piontek, HTL(ASCP)CTBS(AATB)> NIBRI

> Alcohol coagulates proteins on-the-spot, complete with any covalently bound fluorescent tags. This was established for lectin histochemistry 30 years ago, and has been well documented for fluorescently labelled antibodies in more recent years. The intensity of  fluorescence emission may be less in DPX than in buffered glycerol, but who has done comparisons?
