Quantitation of specific antibodies in the aqueous humor

Six normal rabbits were injected intravitreally with bovine gamma-globulin (BGG). Quantitation of immunoglobulins A, M and G, in the aqueous and in the serum, was performed by the single radial immunodiffusion following the method described by MANCINI et. al. Concentration of anti-BGG antibodies was determined by the reversed Mancini method. The antibody quotient was calculated; it reached to 8 and 5.96 in the aqueous of the injected eyes 10 days after intravitreal injection, 22.69 and 24 days, 22.52 after 28 days and 14.93 after 31 days.
