What are antibody markers?

Antibody markers are antibodies that are used to identify and/or characterize specific proteins or molecules.

Antibodies are produced by the immune system in response to the presence of foreign substances, such as bacteria, viruses, or toxins. These antibodies bind to specific antigens, which are molecules that are present on the surface of these foreign substances.

Antibody markers are antibodies that have been designed to bind to specific proteins or molecules of interest. They are often used in research and diagnostic applications, such as:

* Immunohistochemistry: This technique is used to identify and locate specific proteins within cells or tissues.

* Western blotting: This technique is used to separate and identify specific proteins in a sample.

* ELISA (enzyme-linked immunosorbent assay): This technique is used to quantify the amount of a specific protein in a sample.

* Flow cytometry: This technique is used to measure the expression of specific proteins on cells.

Antibody markers can be highly specific, and they can detect even very small amounts of target protein. This makes them a valuable tool for research and diagnostic purposes.
