The universal stain for cytological preparations is the Papanicolaou stain. May-Gr\xfcnwald Giemsa Stain is one of the common Romanwsky stains used in cytology. It is useful for studying cell morphology in air-dried smears..
What are the reagents and stains used in cytology?
Specialized stains such as Propidium Iodide Solution, Masson's Trichrome Stain Kit, Schiff Reagent Solution, and many others are available. Accompanying reagents, QuenchShield™ Mountant, Antigen Retrieval Solution, Citrate (pH 6.0) [5.
X], Neutral Buffered Formalin 10% are also offered
What is a dye used for in cytology?
Acid Fuchsin is one of the dyes used in the Masson's Trichrome Staining technique. This method is commonly used to stain tissue sections in the Histology and Cytology Laboratory in order to distinguish muscle from collagen..
What is routine and special stain in cytology?
Routine staining refers primarily to the hematoxylin and eosin (H&E) stain, while special staining is used to refer to alternative staining techniques outside of routine H&E stain to provide specific information researchers or pathologists need..
What is the cytological staining method?

STAINING IN CYTOLOGY The universal stain for cytological preparations is the Papanicolaou stain.
Harris' hematoxylin is the optimum nuclear stain and the combination of OG6 and EA50 give the subtle range of green, blue and pink hues to the cell cytoplasm.
What stains are used in exfoliative cytology?
These smears are then stained with various stains like hematoxylin and eosin, papanicolaou, periodic acid Schiff, silver salts and are observed under microscope to interpret the dysplastic nature of cells..
[1] The initial Pap stain was later modified by him in 1954 and 1960. It yields a polychromatic, transparent staining reaction with crisp nuclear and cytological features, which can be easily interpreted by a trained pathologist. [2] The Pap stain has been most frequently used for screening of cervical cancer.
The general steps for a cytological staining per-se are the following ones:
Fixation: the cytology smears are fixed in 95% ethyl alcohol or other substitutes for a minimum of 15 minutes.
Staining: the cytological staining differentiates cells structures playing with different dyes.
The universal stain for cytological samples is the PAP stain developed by the Greek cytopathologist, George Papanico- laou. He developed the polychrome staining reaction to study cell components, variations in cellular maturity, and metabolic activity.
To perform a cytology staining, stains reveal the structures of the cells to examine such as the nucleus, the cytoplasm, and cellular granules. Experience is necessary to obtain an optimal smear, a fine balance between too thick and too thin smears. After preparing the smears, fixation, and staining is essential.
What Kinds of Cytology Are there?
There are two main kinds, or branches, of cytology: exfoliative cytology and intervention cytology. Healthcare providers can use cytology tests for almost all areas of your body. Some common types of cytology tests include:. 1) Gynecologic cytology.. 2) Urinary cytology.. 3) Breast cytology. 4) Thyroid cytology. 5) Lymph node cytology. 6) Respiratory .
Cytology stains
Stain used for diagnosis of malaria
Giemsa stain, named after German chemist and bacteriologist Gustav Giemsa, is a nucleic acid stain used in cytogenetics and for the histopathological diagnosis of malaria and other parasites.
In pathology
In pathology, the Grocott–Gömöri'smethenamine silver stain, abbreviated GMS, is a popular staining method in histology. The stain was originally named after György Gömöri, the Hungarian physician who developed the stain.
Mallory's trichrome stain also called Mallory's Triple
Mallory's trichrome stain also called Mallory's Triple Stain is a stain utilized in histology to aid in revealing different macromolecules that make up the cell. It uses the three stains: aniline blue, acid fuchsin, and orange G. As a result, this staining technique can reveal collagen, ordinary cytoplasm, and red blood cells. It is used in examining the collagen of connective tissue.
May–Grünwald stain
May–Grünwald stain or May–Grünwald–Giemsa stain is used for the staining of slides obtained by fine-needle aspiration in a histopathology lab for the diagnosis of tumorous cells.
Papanicolaou stain is a multichromatic (multicolored) cytological staining
Histological staining method
Papanicolaou stain is a multichromatic (multicolored) cytological staining technique developed by George Papanicolaou in 1942. The Papanicolaou stain is one of the most widely used stains in cytology, where it is used to aid pathologists in making a diagnosis. Although most notable for its use in the detection of cervical cancer in the Pap test or Pap smear, it is also used to stain non-gynecological specimen preparations from a variety of bodily secretions and from small needle biopsies of organs and tissues. Papanicolaou published three formulations of this stain in 1942, 1954, and 1960.
Romanowsky staining
Family of related stains for examination of blood including the detection of parasites
Romanowsky staining, also known as Romanowsky–Giemsa staining, is a prototypical staining technique that was the forerunner of several distinct but similar stains widely used in hematology and cytopathology. Romanowsky-type stains are used to differentiate cells for microscopic examination in pathological specimens, especially blood and bone marrow films, and to detect parasites such as malaria within the blood. Stains that are related to or derived from the Romanowsky-type stains include Giemsa, Jenner, Wright, Field, May–Grünwald and Leishman stains. The staining technique is named after the Russian physician Dmitri Leonidovich Romanowsky (1861–1921), who was one of the first to recognize its potential for use as a blood stain.
Staining is a technique used to enhance contrast in samples
Technique used to enhance visual contrast of specimens observed under a microscope
Staining is a technique used to enhance contrast in samples, generally at the microscopic level. Stains and dyes are frequently used in histology, in cytology, and in the medical fields of histopathology, hematology, and cytopathology that focus on the study and diagnoses of diseases at the microscopic level. Stains may be used to define biological tissues, cell populations, or organelles within individual cells.
