Pyronin is used in which staining procedure?

Explanation:
Pyronin Y binds to RNA, staining nucleic acids and cytoplasm a magenta/red color. In the Masson–Gomori Pyronin (MGP) staining method, Pyronin Y is used as the RNA/cytoplasmic counterstain alongside the Gomori trichrome dyes. This combination highlights RNA-rich cellular material and provides contrast against muscle and collagen, aiding differentiation of tissue components and assessment of cellular detail. The other stains rely on different dye sets and do not include Pyronin Y.
