Walther Flemming made use of aniline dyes to find a structure in the cell nucleus which strongly absorbed basophilic aniline dyes, which he named chromatin (later called chromosomes). Basophilic is a technical term used by histologists. It describes the microscopic appearance of cells and tissues, as seen down the microscope, after a histological section has been stained with a basic dye. The most common such dye is haematoxylin.
What else can I help you with?
Wrights stain or other stains?
Wright's stain is a Romanowsky stain used in medical laboratories to differentiate blood cells for microscopy. Other stains used for blood cell differentiation include Giemsa stain, Leishman stain, and Hematoxylin and eosin stain. Each stain has specific applications and staining properties.
What is a simple stain reagent?
A simple stain reagent is a type of stain, such as crystal violet or methylene blue, that is used to colorize cells or tissues for microscopic examination. These stains bind to cells and provide contrast to make them visible under a microscope. Simple stains are a quick and easy method to visualize the basic morphology and structure of cells.
What is the secondary stain in gram stain procedure?
It is crystal violet & stains all cells purple.
Why use of ramanowsky stain?
Romanowsky stains, such as Wright's stain and Giemsa stain, are commonly used in the laboratory setting for staining blood smears to visualize and differentiate various blood cells like red blood cells, white blood cells, and platelets. These stains provide contrast that allows for easy identification of cell types and abnormalities under the microscope. They are versatile and widely utilized in hematology and microbiology.
The name given to a liquid used to make cells structures easier to see?
A stain is a liquid used to make cell structures easier to see by adding color contrast. Stains can highlight specific parts of cells, making them more visible under a microscope. Different stains target different cell components or characteristics.

Is diff-quick stain stains RBCs pink and WBCs purple?
Yes, that's correct. Diff-Quik stain stains red blood cells pink and white blood cells purple due to differences in the staining properties of these cells. This differential staining helps in distinguishing between the two types of blood cells under a microscope.

What is an orthochromic stain?
An orthochromic stain is a histological stain used to color specific elements of cells or tissues in microscopy. It typically stains components such as erythrocytes or granules containing hemoglobin in shades of pink or red. These stains are useful for distinguishing different cell types or structures.
What advantages of negative stain?
Since heat fixation is not required and cells are not subjected to the distorting effects of chemicals and heat, their natural size and shape can be seen. Also, it makes it possible to view hard to stain bacteria such as spirilli.
What is advantage of using stain?
Using stains on slides help show some details that may be unclear otherwise, especially in cells.
What so endospore stain have in common with the acid-fast stain?
One thing that endospore stains have in common with the acid fast stain is that heat primary stain penetration. Another thing that endospore stains have in common with acid fast stains are counterstain.
What is the purpose of staining an unknown organism?
By doing differential stains on an unknown organism, you can learn more about that organism. One of the most helpful stains would be the Gram stain. The gram stain will differentiate from Gram positive and Gram negative cells, narrowing your bacteria down a lot. Other stains include: Acid-Fast stain, Capsule stain, Endospore stain, and PHB stain.
What kind of stain are used to stain plant and animal cells?
Plant cells are typically stained with dyes like iodine to highlight structures like nuclei and starch granules. Animal cells can be stained with dyes like hematoxylin and eosin to distinguish different cell components like nuclei and cytoplasm. These stains help researchers visualize and study the cells under a microscope.
