Antibodies. Antibodies are proteins made by B cells (part of the body's immune system) with each B cell producing unique antibodies that recognize a specific epitope on the antigen. An antigen is any substance that provokes an immune response – something foreign or toxic to the body.To identify specific proteins in a tissue or cell type of interest, antibody molecules for specific target molecules are exposed to the sample. The binding of these molecules is detected by incubating the sample with a secondary antibody specific for immunoglobulin molecules and conjugated to a fluorophore (for fluorescent detection).
