  2. Staining - Wikipedia

    en.wikipedia.org/wiki/Staining

    Staining is a technique used to enhance contrast in samples, generally at the microscopic level. Stains and dyes are frequently used in histology (microscopic study of biological tissues ), in cytology (microscopic study of cells ), and in the medical fields of histopathology , hematology , and cytopathology that focus on the study and ...

  3. Dispersion staining - Wikipedia

    en.wikipedia.org/wiki/Dispersion_staining

    The dispersion staining is an analytical technique used in light microscopy that takes advantage of the differences in the dispersion curve of the refractive index of an unknown material relative to a standard material with a known dispersion curve to identify or characterize that unknown material. These differences become manifest as a color ...

  4. Golgi's method - Wikipedia

    en.wikipedia.org/wiki/Golgi's_method

    Golgi's method is a silver staining technique that is used to visualize nervous tissue under light microscopy. The method was discovered by Camillo Golgi , an Italian physician and scientist , who published the first picture made with the technique in 1873. [ 1 ]

  5. Negative stain - Wikipedia

    en.wikipedia.org/wiki/Negative_stain

    In microscopy, negative staining is an established method, often used in diagnostic microscopy, for contrasting a thin specimen with an optically opaque fluid. In this technique, the background is stained, leaving the actual specimen untouched, and thus visible. This contrasts with positive staining, in which the actual specimen is stained.

  6. Microscopy - Wikipedia

    en.wikipedia.org/wiki/Microscopy

    Dispersion staining is an optical technique that results in a colored image of a colorless object. This is an optical staining technique and requires no stains or dyes to produce a color effect. There are five different microscope configurations used in the broader technique of dispersion staining.

  7. Immunostaining - Wikipedia

    en.wikipedia.org/wiki/Immunostaining

    Immunohistochemistry or IHC staining of tissue sections (or immunocytochemistry, which is the staining of cells), is perhaps the most commonly applied immunostaining technique. [2] While the first cases of IHC staining used fluorescent dyes (see immunofluorescence ), other non-fluorescent methods using enzymes such as peroxidase (see ...

  8. Immunogold labelling - Wikipedia

    en.wikipedia.org/wiki/Immunogold_labelling

    Immunogold labeling or immunogold staining (IGS) is a staining technique used in electron microscopy. [2] This staining technique is an equivalent of the indirect immunofluorescence technique for visible light.

  9. Trichrome staining - Wikipedia

    en.wikipedia.org/wiki/Trichrome_staining

    Trichrome staining is a histological staining method that uses two or more acid dyes in conjunction with a polyacid. Staining differentiates tissues by tinting them in contrasting colours. It increases the contrast of microscopic features in cells and tissues, which makes them easier to see when viewed through a microscope.
