Which of the cells are stained with safranin?
The safranin is employed as a counter-stain in endospore staining and Gram’s staining. It is mostly utilized for the identification of cartilage, mucin, and mast cell granules. The safranin stain works by binding to acidic proteoglycans in cartilage tissues with a high affinity forming a reddish orange complex.
Does safranin stain human cells?
Primary stain, all bacteria are stained purple. This stains decolorized bacteria red. Human cells can be stained with crystal violet and safranin, so why can’t human cells be gram stained?
Why we use methylene blue in cheek cells?
Human cheek cells can be observed under a microscope after staining with methylene blue dye. Since methylene blue (cationic in nature) binds with DNA and RNA (anionic in nature) by electrostatic means, it gives a darker blue color to nucleic materials as represented in the image given below.
