fuchsin

(fyo͞ok`sĭn) or

magenta

(məjĕn`tə), bright red dyestuff consisting of the mixed hydrochlorides or acetates of rosaniline and pararosaniline. It is composed of small crystals possessing a brilliant green sheen; when dissolved they produce a red solution, which dyes animal fibers directly and vegetable fibers after mordanting. The solution is used in the textile and leather industries and as a stain in biology.

[′fyük·sən]
(organic chemistry)
C20H19N3 Brownish-red crystals, used as a dye or in the commercial preparation of other dyes, and as an antifungal drug. Also known as magenta; rosaniline.

Note that color reaction was performed using new fuchsin (red), and brown pigments were hemosiderin or ceroid.
Cellular colonization and matrix deposition were observed using hematoxylin and eosin (H&E), sGAG deposition was evaluated using aldehyde fuchsin and 1% alcian blue 8GX in 0.1 M HCl, and collagen distribution was assessed using picrosirius red (all from Sigma-Aldrich, Ireland).
After incubation, 2-3 [micro]l of carbol fuchsin dye to stain Mycobacterium cells and crystal violet to stain epithelial cell were added to each tube and the mixture was gently shaken.
The RNTCP recommend 1% Carbol Fuchsin (CF) as primary staining reagent, 25% sulphuric acid ([H.sub.2] S[O.sub.4]) for destaining and 0.1% methylene blue (Mb) as counter staining reagent.
Aerospray stainers are dual-purpose staining and cell preparation systems for staining hematology smears with water-based or methanol-based stains, or TB smears with carbol fuchsin or fluorescence stains.
After dewaxing and gradient ethanol hydration, kidney sections (3 [micro]m) were stained with Weigert's hematoxylin solution for 10 min, rinsed in distilled water for 5 min, stained with Masson ponceau acid fuchsin solution for 10 min, rinsed in distilled water for 2 min, placed in 1% phosphomolybdic acid solution for 5 min, and immersed in aniline blue solution for 5 min.
Demonstration of collagen and elastic fibres was done by using Van Gieson's stain (Mallory, 1961) and Gomori's Aldehyde Fuchsin method (Gomori, 1946) respectively.
