pyronin
py·ro·nin P5750500 (pī′rə-nĭn) also py·ro·nine (-nēn′)n. Any of a group of xanthene dyes used as a biological stain, especially to detect or track the presence of RNA by staining it red.
[German Pyronin, originally a trademark.]pyronin (ˈpaɪrəʊˌnɪn) or pyroninen1. (Chemistry) either of two synthetic red xanthene dyes, pyronin G or Y and pyronin B, used chiefly as microscopic stains 2. (Biology) either of two synthetic red xanthene dyes, pyronin G or Y and pyronin B, used chiefly as microscopic stains
pyronin
pyronin [pi´ro-nin] a red aniline histologic stain.py·ro·nin (pī'rō-nin), A fluorescent red basic xanthene dye, the chloride of tetramethyldiaminoxanthene, pyronin Y or pyronin G (C.I. 45005), or of tetraethyldiaminoxanthene, pyronin B (C.I. 45010). These dyes, especially pyronin Y, are used in combination with methyl green for differential staining of RNA (red) and DNA (green); difference in staining result is probably due to the higher degree of polymerization of DNA; pyronin Y is also used as a tracking dye for RNA in electrophoresis.pyronin (pī′rə-nĭn) also pyronine (-nēn′)n. Any of a group of xanthene dyes used as a biological stain, especially to detect or track the presence of RNA by staining it red. py·ro·nin (pī'rō-nin) A fluorescent red basic xanthene dye, used in combination with methyl green for differential staining of RNA (red) and DNA (green); also used as a tracking dye for RNA in electrophoresis. |
