- Stains for argentaffin cells, granules, carcinoid tumors, and melanin in 60 minutes.
- Argentaffin cells possess the ability to bind and reduce silver to a visible metal without requiring a reducing agent, allowing this stain to be performed with fewer steps than other silver stains. An Ammoniacal Silver Developer Solution serves as the primary stain, producing brown to black melanin granules against a pink to red background counterstained by Nuclear Fast Red. There is no filtration required when using MasterTech Nuclear Fast Red.
