What is the standard stain for biological tissues?
Eosin and methylene blue are used for staining biolgical tissues.
What is basophilic degeneration?
blue staining of connective tissues when haematoxylin-eosin stain is used; found in such conditions assolar elastosis.
Alternative stain of hematoxylin eosin stain?
In 1970s, due to clear felling of forests in Brazil and Central America, there was a shortage of logwood and therefore of haematoxylin. Its price went to record heights, which affected the cost of diagnostic histopathology, and prompted a search for alternative nuclear stains. Before the use of any alternatives became firmly established, haematoxylin returned to the market, though at a higher price, and resumed its place in histopathology. There were several dyes recommended as replacements: Celestine blue B (CI 51050), Gallocyanin (CI 51030), Gallein (CI 45445) and Solochrome cyanin (CI 43820). All four used Fe(III) as the mordant. Another alternative is the red dye brazilin, which differs from haematoxylin by only one hydroxyl group for eosine alternate you can ues other compound,There are actually two very closely related compounds commonly referred to as eosin. Most often used is eosin Y (also known as eosin Y ws, eosin yellowish, Acid Red 87, C.I. 45380, bromoeosine, bromofluoresceic acid, D&C Red No. 22); it has a very slightly yellowish cast. The other eosin compound is eosin B (eosin bluish, Acid Red 91, C.I. 45400, Saffrosine, Eosin Scarlet, or imperial red); it has a very faint bluish cast. The two dyes are interchangeable, and the use of one or the other is a matter of preference and tradition
What is the function on bile in Eosin Methylene Blue agar?
To make the Eosin Methylene BLue Agar look cool and hip.
What function of emb agar?
function of eosin methylene blue agar (EMB)
Staining preparation with eosin and methylene blue?
Eosin is a red stand and methylene blue is blue. The result of staining a bacterial smear with a mixture of eosin and methylene blue is that eosin is acidic and acts as a negative stain. Methylene blue is basic the smear background would turn out red while the cells would turn out blue.
What is the composition of leishman stain?
Polychromed methylene blue Eosin Azure Leishman powder Alcohol free absolute alcohol

What kind of stain use in histology?
It depends on what tissue you're looking at, what you want to stain, how the tissue has been stored... Besides very specific staining, there are different types of staining. For example, immunohistochemistry, which uses antibodies to stick coloured stains to cell surface receptors. Or, chemical staining - the most common is H&E staining (haemotoxylin & eosin), so if you're just having fun in a lab and want to see general structures of cells, use this one.
What is a non vital staining?
A stain which isappliedto the dead cells are known as non vital stain for example eosin. aniline blue, orange G etc.
What is the difference between gram's stain and wright's stain?
Wright's Stain is a mixture of methylene blue and eosin in methanol. Gram's stain is crystal violet, iodine washed with acetone and proofed with a safranin dye to look for gram negative organism.
What is Eosin Dye?
It is a dye found in Eosin-methylene blue (EMB) agar, which permits the differentiation between enteric lactose fermenters and nonfermenters. The dye methylene blue inhibits the growth of gram positive bacteria. While the eosin acts as a pH indicator, measuring the levels of acid production due to the fermentation of lactose.Eosin is a stain that is used for staining the cells to observe the structurea nd number of cells. It is an acidophilic stain.
What is basophilic degeneration?
blue staining of connective tissues when haematoxylin-eosin stain is used; found in such conditions assolar elastosis.
What is the structural characteristic of a eosinophils?
They contain a bilobed nucleus and their granules stain red, due to the eosin dye. Plus, the granules themselves look almost crystalline. Don't get them confused with basophils which also have a bilobed nucleus BUT basophils granules do not stain well (and when they do they stain blue) in comparision.

What is the differences between eosin and hematoxylin?
HAEMATOXylin colors nuclei blue while EOSIN colors tissues, cells, or organelles pink and it also binds to proteins which makes H & E stain combination very successful in identifying structures of tissues, nuclei, cells, etc
Is counterstain a negative stain?
Yes. Eosin and acid fuchsin are also acidic dyes like nigrosin.
