Immunoassays are methods for detecting and quantifying analytes within a biological sample based on specific antigen-antibody reaction. They have been widely used in scientific research and ...

Osaka, Japan – Protein detection based on antigen–antibody reaction is vital in early diagnosis of a wide range of diseases. How to effectively detect proteins, however, has frequently bedeviled ...

The principle of an immune assay is based on competitions between a fixed amount of labeled analyte and a variable amount of unlabeled sample analyte for binding a limited number of binding sites of ...

A hypersensitivity reaction happens when the immune system mistakenly identifies harmless substances as harmful. There are several types of hypersensitivity reactions, depending on the class of ...

Antigens and antibodies play vital but distinct roles in illness and disease. One tries to wreak havoc on our health while the other fights to protect it. Simply put, antigens can make you sick, and ...

THE similarities between the effects of the classic anaphylactic reactions and the reactions induced by antigen–antibody complexes suggest that there may be a similarity in the mechanisms responsible ...

One is widespread but has key shortages across its supply chain. One remains questionably reliable and is only helpful after the fact. And one is still early in development – but could speed up and ...

People often talk about COVID-19 testing like it means only one thing. But in reality, the U.S. Food and Drug Administration (FDA) has so far granted emergency-use authorization to more than 200 ...

Antibodies are disease-fighting proteins that play a crucial role in the immune system. Antibodies recognize infectious invaders, such as bacteria and viruses, and help the body eliminate them.

The FDA has issued emergency authorizations to 12 antibody tests for the virus. As federal officials gradually begin reopening the country, expanded testing is central to the conversation. Until now, ...

Several types of antibody-mediated diseases are known. Some are thought to be adverse effects of vaccination, which is logical since vaccines, by definition, cause their effects via stimulation of the ...
