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.
