The following points highlight the top four types of antigen-antibody interaction. The types are: 1. Antibody Affinity 2. Antibody Avidity 3. Cross-Reactivity in Antigen-Antibody Reaction 4. Precipitation Reaction. Type # 1. Antibody Affinity: The strength of the total non-covalent interactions between a single antigen-binding site (idiotope) on an antibody and a single epitope is the affinity of the antibody for [...]
Many clinical tests are being done on the basis of specificity of antibodies for antigen and their ability to recognize epitopes, which is a very small portion or portions of antigen. Antibody based assays are epitope-detecting devices and most of them are based upon the quantitative precipitin curve (Fig. 5.7). A.1 Precipitation reactions in fluids: A quantitative precipitation reaction can [...]
In this article we will discuss about the attributes of acquired immunity. Acquired immunity or Adaptive immune response reflects the presence of a functional immune system that is capable of specifically recognizing and selectively eliminating foreign microorganisms and molecules. Unlike innate immune responses, adaptive immune responses are not the same in all the members of a species, but are specific [...]
