The concentration (or titer) of antibody to a specific antigen can be determined using an ELISA test.
What is the principle of the ELISA test?
The basic principle of the ELISA reaction is the immobilization of one of the reagents on a solid phase, while another reagent can be bound to an enzyme, preserving both the enzymatic and immunological activity of the antibody.
With this information, we can conclude that the concentration (or titer) of antibody to a specific antigen can be determined using an ELISA test.
