Differbetween
The three staining techniques differ in the sample/tissue type: immunofluorescence is commonly used to stain microbiological cells. immunohistochemistry is commonly used to stain sections of biological tissue. immunocytochemistry is commonly used to stain intact cells removed from extracellular matrix.

What is the difference between immunocytochemistry and immunohistochemistry?
Immunohistochemistry is a staining technique that uses entire sections of tissue. Immunocytochemistry is a staining technique that stains individual layers of cells.
What is Immunohistochemistry used for?
After the antibodies bind to the antigen in the tissue sample, the enzyme or dye is activated, and the antigen can then be seen under a microscope. Immunohistochemistry is used to help diagnose diseases, such as cancer. It may also be used to help tell the difference between different types of cancer.
What does immunofluorescence mean?
Immunofluorescence (in short, IF) is a method in biology that relies on the use of antibodies chemically labeled with fluorescent dyes to visualize molecules under a light microscope.
What is the principle of immunohistochemistry?
Immunohistochemistry (IHC) is a method for detecting antigens or haptens in cells of a tissue section by exploiting the principle of antibodies binding specifically to antigens in biological tissues.
What does immunocytochemistry mean?
Listen to pronunciation. (IH-myoo-noh-SY-toh-KEH-mih-stree) A laboratory method that uses antibodies to check for certain antigens (markers) in a sample of cells.
Can IHC antibodies be used for if?
IHC and IF can both be used on frozen or FFPE tissues; however, you tend to get more autofluorescence with FFPE tissues, which can be an issue for IF. Moreover, IHC can have limitations when staining for multiple markers or assessing coexpression.
How long does immunohistochemistry take?
Antigen retrieval
| Heat-induced epitope retrieval | |
|---|---|
| Advantages | Gentler epitope retrieval and more definable parameters. |
| pH | pH 6 buffers are often used, but high pH buffers are widely applicable. Optimal pH must be determined experimentally. |
| Temperature | Approximately 95°C. |
| Incubation time | 10–20 minutes. |
How much does immunohistochemistry cost?
Results: In all scenarios, immunohistochemistry was cost-effective at very low efficacies. Assuming a per-antibody cost of $50 and use of a 5-antibody panel, immunohistochemistry was cost-effective if it resulted in a 1-year gain of population life expectancy in 1 or more of every 200 cases in which it was applied.
How do you do immunohistochemistry?

How is immunofluorescence done?
Immunofluorescence (IF) or cell imaging techniques rely on the use of antibodies to label a specific target antigen with a fluorescent dye (also called fluorophores or fluorochromes) such as fluorescein isothiocyanate (FITC). ... The primary antibody is directly conjugated to a fluorophore.
What is immunofluorescence used for?
Immunofluorescence can be used on tissue sections, cultured cells, or individual cells that are fixed by a variety of methods. Antibodies can be used in this method to analyze the distribution of proteins, glycoproteins, and other antigen targets, including small biological and non-biological molecules.
What is direct immunofluorescence used for?
Direct immunofluorescence (DIF) is a technique used in the laboratory to diagnose diseases of the skin, kidney, and other organ systems. It is also called the direct immune fluorescent test or primary immunofluorescence.
