Test Details
Immunohistochemistry (IHC) is a technique used to detect and localize specific proteins in tissues using antibodies. The IMMUNOHISTOCHEMISTRY GLYCOPHORIN-A Test specifically focuses on Glycophorin-A (GPA), a glycoprotein primarily found on the surface of red blood cells.
The process of immunohistochemistry for glycophorin-A involves several steps:
- Tissue Preparation: Tissue sections are prepared from formalin-fixed, paraffin-embedded blocks or frozen tissues. These sections are mounted on glass slides.
- Antigen Retrieval: Formalin-fixed tissues require antigen retrieval to unmask the protein epitopes. This is done by treating the tissue sections with heat or enzymatic methods.
- Blocking: Non-specific binding sites on the tissue sections are blocked using a protein blocking agent, such as bovine serum albumin or normal serum.
- Primary Antibody Incubation: A primary antibody specific to glycophorin-A is added to the tissue sections and incubated overnight at a specific temperature. The primary antibody binds to the glycophorin-A protein in the tissue.
- Secondary Antibody Incubation: After washing away unbound primary antibody, a secondary antibody is added. The secondary antibody is conjugated with a marker, such as an enzyme (e.g., horseradish peroxidase) or a fluorescent dye.
- Visualization: The marker on the secondary antibody allows for visualization of the bound primary antibody. Enzyme-based markers produce a colored reaction product when a substrate is added, while fluorescent markers emit light of a specific wavelength when excited by a specific light source.
- Counterstaining: To enhance visualization and provide contrast, the tissue sections may be counterstained with a dye, such as hematoxylin or eosin.
- Microscopic Examination: The stained tissue sections are examined under a microscope to evaluate the presence and localization of glycophorin-A in the tissue.
The IMMUNOHISTOCHEMISTRY GLYCOPHORIN-A Test is commonly used in research and diagnostic settings to study erythroid cells, identify hematopoietic tumors, and differentiate between various types of tumors based on their expression of glycophorin-A. It provides valuable information about the distribution and localization of glycophorin-A in different tissues and can aid in the diagnosis and classification of various diseases.
