Safranin - Wikipedia
WEBSafranin (Safranin O or basic red 2) is a biological stain used in histology and cytology. Safranin is used as a counterstain in some staining protocols, colouring cell nuclei red. This is the classic counterstain in both Gram stains and endospore staining .
Safranin - an overview | ScienceDirect Topics
WEBSafranin is a lipophilic cationic dye which accumulates in mitochondria according to the inside negative potential in energized mitochondria. In the course of this process, safranin undergoes a significant change in absorption and self-quenching of its fluorescence (Åkerman & Wikström, 1976; Perevoshchikova, Sorochkina, Zorov, & Antonenko, 2009).

WEBThe Gram stain uses four stains/reagents: crystal violet, Gram's iodine, ethanol, and safranin. Crystal violet (the primary stain ), enters the peptidoglycan of all bacteria giving them a purple color.
Safranin Staining - Conduct Science
WEBThe safranin staining is the most widely used staining technique for cell differentiation, cell-based assays, and stem cell culture. The safranin stain is commonly used to quantify and identify the acidic proteoglycan and glycosaminoglycan in the cartilage tissues.
The Antibacterial Action of Safranin and Gentian Violet
WEBJul 31, 2022 · Our study found safranin to be 100% effective against Gram-positive bacteria (S. aureus), but it had only 20% efficacy against Gram-negative bacteria (Pseudomonas A). Only a few studies have looked at safranin’s antibacterial activity against microorganisms.

WEBDanish physician Hans Christian Gram developed the Gram staining method in 1884. Gram staining procedure uses four chemicals; crystal violet, iodine, alcohol, and safranin, to stain bacteria. Gram staining is still the cornerstone of bacterial identification and …
Safranin O - an overview | ScienceDirect Topics
WEBSafranin O is a general stain for cellulosic materials (red). It is used as a 0.5–1% solution in water or 50% ethanol. Pulp stains are described in detail in Graff (1940), Isenberg (1967), and TAPPI Standard T401 om-82.
