Antigens and antibodies bind by weak forces such as hydrogen bonds, ionic bonds, hydrophobic interactions, and van der Waal's forces rather than covalent bonds. The strength of this noncovalent...

Radioimmunoassay (RIA) is very sensitive (can detect at a concentration of <0.01 μg/mL) and a specific technique that is used for the quantitative detection of antigens or haptens. RIA is an...
When a person is infected with a pathogen, antibodies are produced against many epitopes of this pathogen. A subset of these antibodies can block infection by a process called neutralization....
The indirect fluorescent antibody test (IFA) is a semi-quantitative, sensitive, and rapid test to detect specific antibodies or antigens present in the samples. Direct and indirect...
Detection of specific antigens present in the sample (blood, urine, CSF, or stool) using immunologic methods such as precipitin tests, particle agglutination tests, immunofluorescence, ...
Antibodies are glycoproteins produced by our body in response to invading organisms or toxins (antigens). When a pathogen (bacteria, virus, protozoa, or helminth) enters our body and anyhow...
