Antigen Retrieval: Key in Immunohistochemistry (IHC)

Antigen retrieval is essential in immunological techniques such as immunohistochemistry (IHC), as epitopes can be masked during sample preparation and processing. This critical step ensures accurate detection and avoids erroneous results.

Main Methods:

1. Heat-mediated recovery: uses high temperatures to break protein cross-links, exposing epitopes.

2. Enzyme-mediated recovery: Employs proteolytic enzymes to release hidden epitopes.

Advantages of the Heat Method:

·High efficiency in epitope exposure.

·Compatible with various antibodies.

·Significant reduction of preparation time.

·Ease of standardization and maintenance of tissue morphology.

·Integration with automated technology.

Selection of buffers according to the type of epitope:

·Linear Epitopes: Recovery Buffer (pH 7.4).

·Structural Epitopes: Universal Buffer (pH 9.0).

·Hidden Epitopes: T-Universal Buffer (pH 7.4).
