Perhaps the most common use of eosin dye is in blood testing.
Technicians mix the dye with a small amount of blood,
then count how many cells absorb the fluorescent red dye.
Several serious diseases cause a count of more than 500 eosinophils/microlitre of blood.
The blue stain is called crystal violet. It can color the bacteria a blue color only if the cell wall is very thick. We then call that bacteria a Gram+ bacteria. Knowing the Gram test (+ or-) and the shape of the bacteria, we have a quick idea of what it might be. Then what antibiotic could be given gives a head start on a treatment. This can take as little as a few minutes. Further tests are usually done later on. They can take 24 to 36 hours to get a result.
Well, sweetheart, Gram's stain is used to differentiate bacteria into two groups based on their cell wall composition - either Gram-positive or Gram-negative. On the other hand, Wright's stain is a Romanowsky stain used in hematology to stain blood cells for microscopic examination. So, in a nutshell, one is for bacteria and the other is for blood cells. Hope that clears things up for you, darling.
Eosin is a red/pink acidic dye used in histology to stain cytoplasmic components such as proteins and muscle fibers. It is often used in combination with hematoxylin to provide contrast in tissue samples for microscopic examination. Eosin is commonly used in the H&E (hematoxylin and eosin) stain, one of the most widely used staining techniques in pathology.
The name of the fluorescent red dye is eosin
Eosin (disodium 2-(2,4,5,7-tetrabromo-6-oxido-3-oxo-3H-xanthen-9-yl) benzoate) is prepared in laboratory.

Eosin is a type of dye used in microscopic examinations. The purpose of adding eosin to the root hair of an onion is to make it easier to distinguish different characteristics of the root hair of an onion underneath the view of a microscope.

The fluorescent red dye formed by the action of bromine on fluorescein is called eosin Y. It is commonly used as a histological stain for tissues and as a pH indicator in chemical laboratories. Eosin Y appears red under visible light and emits a strong fluorescent signal when exposed to ultraviolet light.
Eosin dye is generally considered safe for use in laboratories and medical settings. However, as with any chemical substance, precautions should be taken to avoid skin contact or inhalation. It is important to follow proper safety guidelines when handling eosin dye to minimize any potential risks.
