CONTROL: For staining fungus; use a known positive such as those used for the GMS. Use skin, aorta or normal liver for positive PAS staining

  1. The periodic acid-Schiff (PAS) stain indicates the presence of intracellular glycogen and neutral mucopolysaccharides. Cells of many series are positive for PAS, however the staining pattern differs. Erythroleukemias ie AML M6 blasts show an intense diffuse cytoplasmic positivity with PAS, while lymphoblasts show block positivity
  2. Answer. Periodic acid-Schiff (PAS) stain findings are usually positive in erythroblasts and abnormal erythroid precursors and negative in normal erythroid precursors of all stages of maturation
  3. Periodic acid. Periodic acid-Schiff ( PAS) is a staining method used to detect polysaccharides such as glycogen, and mucosubstances such as glycoproteins, glycolipids and mucins in tissues. The reaction of periodic acid oxidizes the vicinal diols in these sugars, usually breaking up the bond between two adjacent carbons not involved in the.
  4. What is Periodic Acid-Schiff (PAS) Staining? Periodic-Acid Schiff (PAS) staining technique is used in histochemistry and histological studies to demonstrate the presence of carbohydrates and carbohydrate compounds such as polysaccharides, mucin, glycogen, and fungal cell wall components

  1. Cytochemical stains (periodic acid-Schiff [PAS], Sudan black B [SBB], a-naphthyl acetate esterase [ANAE], acid phosphatase [AcP], and p-glucuronidase [p-glu]), and scanning and transmission electron microscopy were done using standard techniques. Results — Eighteen snakes (64.3%) were positive for Hepatozoon infection
  2. Repetition of GMS stain on these three cases (cutting in a deeper level in the paraffin block) resulted in positive results. Four out of 30 cases were negative with original PAS stain, but stained positive both with new PAS and GMS. Conclusions: PAS and GMS stains are quantitatively similar. Sensitivity of both methods can be increased by.
  3. There is a tendency for this stain to produce a lot of artefact from background staining, so it is essential to be sure of the morphology of the organism being sought.

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.

  1. Cytochemistry Methods, Specific Techniques and Stains in Microscopy What is Cytochemistry? In cell biology and biology in general, cytochemistry is the study of the (bio-chemical) chemical constituents of the cell. Using cytochemistry, it has also become possible for scientists and technicians to localize various chemical components or elements, which may be enzymatic or non-enzymatic in nature
  2. The Internet Journal of Hematology. 2002 Volume 1 Number 1. DOI: 10.5580/1bd3. Abstract. Myeloperoxidase (MPO) and Periodic acid schiff's ( PAS) are the two basic cytochemical stains, commonly used in diagnosis and typing of acute leukemias. Combined cytochemistry with MPO & PAS can be done in same smear and may have some practical value where.
  3. The rhodanine, orcein, and Timm stains for copper are used in the characterization of chronic cholestatic liver disease and Wilson's disease. Labeling of carbohydrate-based moieties in various disorders is accomplished with the digested and undigested periodic acid-Schiff method, and Congo red or crystal violet stains can be employed to detect.
  4. Cytochemical Stains. Two cytochemical stains are performed in the hematopathology laboratory. These studies can be performed on unstained peripheral blood or bone marrow aspirate smears, anticoagulated peripheral blood or bone marrow aspirate material. Myeloperoxidase (MPO) The myeloperoxidase stain is positive in cells of the granulocyte series
  5. The Giemsa stain is commonly used in hematology for its superior ability to stain bone marrow, plasma cells, and mast cells. It is also very popular for identifying blood parasites. [3] The Giemsa stain can also help to visualize chromosome abnormalities through Giemsa-Based Banding, or observing the alternating darker and lighter nucleotide.
  6. Myeloperoxidase is a lysosomal enzyme present in the primary azurophilic granules of neutrophils, eosinophils and to a certain extent, monocytes. Lymphocytes do not contain myeloperoxidase. Purpose of Myeloperoxidase stain. Myeloperoxidase (MPO) stain is useful for differentiating the blasts of acute myeloid leukemia (AML) from those of acute lymphoblastic leukemia (ALL)
