12 Differences between antigen and antibody (Antigen vs Antibody)

July 8, 2020March 26, 2018 by Sagar Aryal

Differences between antigen and antibody Antibodies are produced by the immune system in response to antigens (material perceived as foreign). The antibody response to a particular antigen is highly specific and often involves a physical association between the two molecules. This association is governed by biochemical and molecular forces. The reaction between antigens (Ags) and antibodies (Abs) involves complementary binding sites …

Introduction to Antigen-Antibody Reactions

October 9, 2020October 13, 2017 by Sagar Aryal

Introduction to Antigen-Antibody Reactions The interactions between antigens and antibodies are known as antigen–antibody reactions. The reactions are highly specific, and an antigen reacts only with antibodies produced by itself or with closely related antigens. Antibodies recognize molecular shapes (epitopes) on antigens. Generally, the better the fit of the epitope (in terms of geometry and chemical character) to the antibody …

Antibody- Introduction, Structure and Classes

January 2, 2020October 11, 2017 by Sagar Aryal

Antibody- Introduction, Structure and Classes Antibodies are often referred to as immunoglobulins (immune proteins). Antibodies, or Y-shaped immunoglobulins, are proteins found in the blood that help to fight against foreign substances called antigens. Antigens, which are usually proteins or polysaccharides, stimulate the immune system to produce antibodies. The antibodies inactivate the antigen and help to remove it from the body. While …
