Staining & Mounting Flashcards
Components are demostrated by DIRECT INTERACTION with Dye or staining solution
HISTOLOGICAL STAINING
Components are studied through chemical reaction; for demonstration of CHEMICAL COMPONENTS
Histochemical / Histochemistry staining
Histochemical staining used for HEMOGLOBIN
Pearl’s Prussian Blue reaction
Histochemical staining used for Carbohydrates
Periodic Acid Schiff
Demonstrate tissue ANTIGEN
Immunohistochemical staining
This is a combination of immunologic and histochemical staining
Imunnohistochemical staining
Detection of phenotypic markers that are detected by antibody
Immunohistochemical
Staining technique that uses aqueous or alcoholic dye to produce color
Direct Staining
Type of staining techniques that uses one dye and color of the dye is usually the resulting color
TISSUE + DYE = COLOR
Direct Staining
Type of staining that uses MORDANT or ACCENTUATOR to produce color
Indirect Staining
Substance that serves as the link/bridge between the dye and the tissue
MORDANT
EXAMPLES OF MORDANT
Erlich
Cole
Mayers
Gills
ALUM ( potassium alum)
Iron
- Heidenhain = ferric ammonium sulfate
- Weigerts = ferrim ammonium chloride
Copper = copper
PTAH = phophotungstic acid
ALL ARE HEMATOXYLINS
Substance that INCREASES you he color intensity and selectivity of the dye
ACCENTUATOR
EXAMPLES OF ACCENTUATOR
KOH
Phenol in carbol fuchsin and carbol thionine
Staining technique that use gradual application of dye. Tissue elements is re-stained in DEFINITE SEQUENCE
Progressive staining
Dye is applied little by little until desired color is achieved
Progressive staining
This staining technique do not need DECOLORIZATION
Progressive staining
Tissue is overstained and excess dye should be removed using DECOLORIZATION
Regressive staining
Selectively removal of excess of dye
DECOLONIZATION OR DIFFERENTIATION
This is the most common DECOLORIZATION substance and can remove both ACID and BASIC dye
ACID ALCOHOL
This of type of staining technique that involves application of different color to produce contrast and background
counterstaining
This of type of staining technique that involves application of different color to produce contrast and background
counterstaining
Type of staining technique that stained tissue with a color that is DIFFERENT from the stain itself
Metachromatic staining
Which stain is not belong to Metachromatic staining
Methyl violet
Cresyl blue
Safranin
Nile blue
Methylene blue
Nile blue
This staining technique stained tissue with the SAME SHADE /HUE as that if the dye
Orthochromatic staining
Type of staining technique that is Selective to living cells
Vital staining
Two types of Vital staining
Intravital & Supravital
The dye/stain is so injected directly to any part of the LIVING BODY
Intravital
Stains is applied immediately to the tissue after its REMOVAL from living body
Supravital
Best vital stain
Neutral red
Especially recommended for MITOCHONDRIA under supravital staining
Janus green
type of staining technique that DO NOT USE DYE instead use METALLIC SALTS
Metallic IMPREGNATION
Leaves black deposits on the surface of the tissue
Metallic impregnation
Which of these metallic salt cannot be used?
Ammoniacal silver
Silver nitrate
Ammoniacal gold
Gold chloride
Ammoniacal gold
(There is no ammoniacal gold)
Most common method that utilized MICROANATOMICAL STUDIES OF TISSUE
H&E Staining
Dye used in cytoplasmic stain; counterstaining
EOSIN
TRUE OR FALSE
tissue fixed with mercuric chloride staining time should be DECREASED slightly while duration of eosin should be INCREASED
False
staining time should be INCREASED
duration should be REDUCED
H&E result color for Nuclei
Blue to blue black
H&E color result for Karyosome
Dark blue
H&E color result for Cytoplasm
Pale pink
H&E color result for RBC and Eosinophilic granules
Keratin-bright orange red
H&E color result for Calcium and decalcified bone
Purplish blue
H&E color result for decalcified bone MATRIX, collagen and osteoid
PINK
H&E color result for muscle fibers
Deep pink
what are the staining methods for FROZEN section
H&E
Thionine
Polychrome methylene blue
Alcoholic pinacyanol method
Derived from plants and animals
Natural Dyes
Not a stain, active coloring agent is HEMATEIN
Hematoxylin
Mordant of hematoxylin
Alum, iron, copper, chromium
Hematoxylin mordant that is also a general for photomicrography
Iron hematoxylin
Under alum hematoxylin, ripening agents for exfoliative cytology and demonstration of sex chromosome
Harris hematoxylin
Under alum hematoxylin a ripening agent that use sodium iodate with citric acid & chloral hydrate as preservative for immunohistochemistry
Mayers hematoxylin
Mordant of Weigert’s hematoxylin for muscle fibers and CT
Ferric ammonium CHLORIDE
Mordant of Heidenhain’s hematoxylin for nuclei &cytoplasmic inclusion
Ferric ammonium SULFATE
Demonstrate spermatogenesis
Copper hematoxylin
Demonstrate endocrine cells of alimentary tract
Lead hematoxylin
Demonstrate of collagen, reticulin and argentaffin cells
6 Molybdenum hematoxylin
Extracted from bug (Coccus cacti)
