Alizarin red S (sodium alizarin sulfonate) method is a reliable stain for
calcium salts and or crystals. Calcium deposits become birefringent with a
2% aqueous alizarin red S, adjusted with 10% ammonium hydroxide to a pH of
4.2. End point staining must controlled microscopically when the calcium
deposits become reddish-orange. A good control would be kidney
hypercalcinosis or breast calcification. I would be glad to fax you a copy
of the procedure by McKee-Russell, if this is the method your pathologist is

One of our pathologists asked us for a Luzerin Red stain for crystals.
Does anyone have any information on this?  Thanks to all in advance.
