method for calcium
04 – 170801

CND Code: W01030799
Expected aim
Product for the preparation of cyto-histological samples for optical microscopy. Application
To demonstrate deposits of calcium ions in tissue sections. Principle
This method is based on a substitution reaction. Tissue is treated with a silver nitrate solution; cationic silver replaces calcium in the original salt thus forming a silver salt which can be showed by a reduction to metallic silver. Reaction is as follows: CaCO3 + AgNO3 = Ag2CO3 + Ca(NO3)2 Ag2CO3 + 2H + = 2Ag + H2O + CO2 Calcium salts liable to react with silver nitrate are: carbonate, phosphate, oxalate, sulfate, urate, chloride, sulfocyanide. Since calcium is present in mammalian tissue essentially in the form of calcium carbonate and calcium phosphate, this method is suitable to point it out. To prevent false results caused by the presence of uric acid and urates in the tissue, these salts have been solubilized in a lithium carbonate saturated solution. Put on the section 10 drops of reagent A : leave to act 10 minutes. Put on the section 10 drops of reagent B: leave to act in the dark 1 hour. Put on the section 5 drops of distilled water and add 10 drops of reagent C: leave to act 5 minutes (Until silver salts become black). Put on the section 10 drops of reagent D: leave to act 5 minutes. 10) Put on the section 10 drops of reagent E : leave to act 5 minutes. 11) Rinse in distilled water and dehydrate through ascending alcohols, clear in xylene and mount.
