S tains for fungi and Pneumocystis jirovecii in just 15 minutes.

This kit includes a 15 minute microwave procedure and the traditional one hour and thirty minute procedure. The MasterTech G.M.S. Staining Kit is suitable in lieu of and comparable to the Grocott Methenamine Silver Technique. The MasterTech G.M.S. Stain Kit differs from this technique through the use of a stabilized, pre-measured Methenamine Silver Compound, instead of Methenamine Borate, Hexamine, or Silver Nitrate Solutions. This benefits the end user through ease of use and a longer shelf life. A Methenamine Silver Developer Solution serves as the primary stain, with Gold Chloride toning the tissue sections, producing gray to black fungi and Pneumocystis jirovecii against a green background counterstained with Light Green.

00ml Stain Kit yields between 20 and 32 slides. Pint Stain Kit yields between 100-400 slides. Liter Stain Kit Yields between 240-800 slides. Slide Yields assume maximum slides stained per run, maximum runs per use. Actual Slide Yields may vary.
