Studies on nonprecipitating antibody. II. Circulating antibody-antigen complex following repeat injections of antigen
Abstract:
Reinjection of antigen into immunized rabbits usually results in an immediate increase of circulating antibody-antigen complex. This immediate formation of complex seems to depend upon the presence of non-precipitating antibody before reinjection. The complex disappears by the 2nd day after reinjection and reappears between the 4th to 7th day. This is earlier than its first appearance after a primary injection and may indicate an anamnestic response of the non-precipitating antibody responsible for the formation of circulating antibody-antigen complex.

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.
