Views: 4866 PAS stain is mainly used to highlight the molecules (structures) with high percentage of carbohydrate content such as glycogen, glycoproteins, and proteoglycans typically found in connective tissue, glycocalyx and basal laminae. PAS staining can be used to assist in the diagnosis of several medical conditions such as Staining a smear Place the smear on the staining rack Pour leishman stain to cover the smear completely allow to fix for 2-3 mien Add water twice the amount of leishman's stain allow to fix for 7-10 mins Appearance of golden scum or sheen on the surface of stain Wash the stain off the slide with running water Wipe the back of slide and air dry the slid
STAINING TECHNIQUE USING GIEMSA STAIN: 1. Prepare a thin blood film as discussed earlier and dry in air. 2. Fix in methanol for 3 minute. 3. Dilute one volume of the solution (Azure II eosin, Azure II, glycerol, methyl alcohol) with 9 volumes of the buffer solution. 4. Flood the slide with the stain and allow to act for 10-15 minutes After reaction with Schiff′s Reagent (a mixture of pararosaniline and sodium metabisulfite), a pararosaniline adduct is released that stains the glycol-containing cellular elements pink to red. Cellular elements which may be demonstrated with the PAS procedure include glycogen, fungal walls, basement membrane, certain epithelial sulfomucins and.
PAS is commonly used on liver tissue where glycogen deposits are made which is done in efforts to distinguish different types of glycogen storage diseases. PAS is important because it can detect glycogen granules found in tumors of the ovaries and pancreas of the endocrine system, as well as in the bladder and kidneys of the renal system Apart from staining malarial parasites, Giemsa stain has a variety of applications in microbiology and pathology: Giemsa stain is used to obtain differential white blood cell counts. It is also used to differentiate nuclear and cytoplasmic morphology of the various blood cells like platelets, RBCs, WBCs
Giemsa stain was a name adopted from a Germany Chemist scientist, for his application of a combination of reagents in demonstrating the presence of parasites in malaria. It belongs to a group of stains known as Romanowsky stains (PAS) Stains glycogen, mucin, fungus, basement membrane and other substances. Stain used to detect fungal organisms and cytoplasmic accumulation of glycogen. Stains glycogen red, used in place of Best's Carmine. Stains lysosomes granules red-purple, can be used in recognition of macrophages In this Article, I'll discuss Giemsa Staining Technique used in Hematology Laboratory. A brief Description of Giemsa Stain. Giemsa stain is a mixture of Azure, Methylene blue, and Eosin dye. Giemsa stain is a differential stain that is used to variably stain the various components of the cells and it can be used to study the adherence of. other stain, acid alcohol treatment is the method of choice. Differentiation In regressive staining differentiation is the removal of washing out of the excess stain until the colour is retained only in the tissue components to be studies. Impregnation It is the deposition of salts of heavy metals on or around cells, tissue constituents etc In cytogenetics it stains chromosomes to facilitate diagnosis of aberrations. Because it distinguishes easily between blood cells, it became widely used for performing differential white blood cell counts, which ar e routinely ordered when infections are expected. There are variants known as buffered Wright stain or Wright-Giemsa stain

Romanowsky stains are universally employed for staining blood films and are generally very satisfactory. There are a number of different combinations of these dyes, which vary, in their staining characteristics. 1. May-Grunwald-Giemsa is a good method for routine work. 2. Giemsa stain is thought to produce more delicate staining characteristics. 3 Med Aid India - Offering Special Stain - PAS Stain, सूक्ष्मदर्शी की स्लाइड at Rs 1000/piece in New Delhi, Delhi.
