An antigen is any substance that can trigger an immune response in the body. Antigens are typically proteins or polysaccharides that are recognized as foreign or potentially harmful by the immune ...

Antibodies, also known as immunoglobulins, are specialized proteins produced by the immune system to identify and neutralize foreign invaders, such as viruses, bacteria, and other pathogens. They are ...

Researchers have developed a novel antibody-based enzyme switch that converts antibody–antigen binding into enzyme activity, paving the way from detection via bioluminescence to the control of ...

Immunoassays are measurement procedures that use immune-based reagents to generate a detectable signal, allowing scientists to quantify biological processes. Scientists perform immunoassays to measure ...
