Blockers and immunoglobulins are both important components in the field of immunology and biomedical research. Blockers are often used to inhibit or prevent certain immune responses or reactions. They can act on receptors, enzymes, or other molecules involved in immune processes. Blockers are valuable tools in research to study the functions and mechanisms of the immune system and can also have therapeutic applications.

Immunoglobulins, also known as antibodies, are proteins produced by the immune system in response to the presence of foreign substances, such as pathogens (e.g., bacteria, viruses) or antigens. Immunoglobulins play a crucial role in immune defense by recognizing and neutralizing these foreign invaders.There are different classes of immunoglobulins, including IgG, IgM, IgA, IgE, and IgD. Each class has unique properties and functions in the immune response.
