Abstract:
New approaches for the measurement of antibody affinity by ELISA are suggested and considered theoretically. It was shown that not only more precise and more convenient in comparison to that suggested earlier, but also more informative graphical representation of the experimental data in the appropriate coordinate could be used for evaluation of antibody affinity. The following cases were considered: (i) determination of antibody affinity for one kind of univalent antibodies, (ii) determination of antibody affinity for one kind of bivalent antibodies, (iii) determination of antibody affinity for two kinds of univalent antibodies, which are in a mixture, and (iv) determination of antibody affinity for two kinds of bivalent antibodies, which are in a mixture. Advantages and disadvantages of the different approaches are discussed.

Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.

Enzyme-Linked Immunosorbent Assay
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen. Enzyme-substrate reaction allows the antigen to be visualized or quantified.
