Description
Safranin Color is used for Plant Juice Extraction Tests in Biology Laboratories. Labtex supplies the best quality Safranin Color Liquid. Safranin Color is called also Safranin Solutions which is a laboratory chemical or laboratory solution.
safranine color is a biological stain used in the Biology Lab for Plant Juice Extraction. Safranin is also used as a counterstain in some staining protocols, histology, cytology & coloring all cell nuclei red.
Safranin is a synthetic dye commonly used in biological staining. It is a bright red or pink dye that belongs to the compounds known as phenazine dyes. Here’s how it is used:
Properties of Safranin:
- Color: Safranin produces a red or reddish-pink color.
- Chemical Nature: It is a cationic (positively charged) dye, meaning it readily binds to negatively charged cell components.
- Solubility: It is soluble in water and alcohol.
Safranin Color Uses in Biology:
- Counterstain in Gram Staining: Safranin is used as a counterstain in Gram staining, a method for classifying bacteria. After the primary stain (crystal violet) and a decolorizing step, Safranin stains the Gram-negative bacteria red or pink while Gram-positive bacteria remain violet.
- Staining Cell Nuclei: Safranin stains cell nuclei red due to its affinity for nucleic acids.
- Plant Tissue Staining: In botany, Safranin is used to stain lignified tissues, like xylem, and red, helping to differentiate between various plant structures.
Staining Protocol:
In a typical protocol (e.g., Gram staining), Safranin is applied as the final step after other staining and decolorization steps. It generally takes 30 seconds to 1 minute for the stain to penetrate the cells.
