What ar the component of acid fast staining?
Periodic acid-Schiff (PAS) is a staining method used in histology and pathology. This method is primarily used to identify glycogen in tissues. The reaction of periodic acid selectively oxidizes the glucose residues, creates aldehydes that react with the Schiff reagent and creates a purple-magenta color. A suitable basic stain is often used as a counterstain.Source: http://en.wikipedia.org/wiki/Periodic_acid-Schiff_stain
Which Stains are used for staining globin chains of hemoglobin?
eosin
Which is the Counterstain used in PAS staining?
The counterstain for PAS is hematoxylin which stains nucleic acids blue.
What advantages of differential staining procedures over the simple staining technique?
Using multiple stains can better differentiate between different microorganisms or structures/cellular components of a single organism.

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 a primary stain?
If your talking about Acid Fast staining (aka Ziehl-Neelsen staining), after the addition of the primary stain (carbol fuchsin) heat is applied in order to facilitate proper staining. Bacteria such as Mycobacterium contain large amounts of lipid substances within their cell wall called mycolic acids. These acids resist staining by ordinary methods such as gram staining (where heat is not applied after primary staining). On application of heat, the stain carbol fuschin penetrates the cell wall and stains the cells pink. Following the secondary staining (methylene blue) the acid fast positive cells appear pink while others are stained blue. Endospore staining is yet another staining technique where heat is applied after primary staining (malachite green). In this case the spores are impermeable to stains, hence heating favours proper permeation of stain. Endospores appear green while vegetative cells appear red (secondary stain saffranine). Not all staining procedures involve applying heat after primary staining. However, heat is applied before even beginning the staining procedure. This is called heat fixing, where the cells are fixed so that they are not washed away during the subsequent washing steps.
Name three basic stains?
methylene blue crystal violet carbol fuchsin
What type of dye is used to stain the specimen when the acid-fast stain and the gram stain are used?
Both processes use 2 stains. The Gram staining process uses crystal violet as the primary stain and safranin as the secondary stain. Acid-fast staining uses carbol fuchsin as the primary and methylene blue as the secondary.
Which Stains are used for staining globin chains of hemoglobin?
eosin
What is the clinical significance of Alcian Blue staining?
It stains basophiles, cartilage, mucopolysaccharides and glycosaminoglycans
Which is the Counterstain used in PAS staining?
The counterstain for PAS is hematoxylin which stains nucleic acids blue.
What is the function of staining jar?
There are several uses for a staining jar. In microscopy, it is used for staining tissues and cells for slides. After being stained with dyes or stains, the specimens can also be placed in the jar to look for certain aspects.

What is the use of Koplin jar in the laboratory?
to hold slides for staining or in between stains to rinse excess away with water
