Specific immunologic tolerance to bovine serum albumin (BSA) was induced in approximately one-half of the rabbits that had been primarily immunized and were prepared for a secondary antibody response to BSA. The state of tolerance lasted for several months in the majority of rabbits and was not easily terminated by immunization with human serum albumin followed by BSA.

Rhamnose and sTn antigen were co-conjugated to bovine serum albumin (BSA) for cancer vaccine development. The immune responses against sTn have been significantly augmented with the involvement of Rha-specific antibodies to enhance antigen uptake.

Rabbits were injected into the hind foot with diphtheria toxoid and bovine serum albumin. Fragments of popliteal lymph node taken from them several months later were placed in plasma-clot cultures with Eagle's medium. When antigen was added to the culture fluid, anamnestic antibody responses occurred regularly. When the antigen was diphtheria, responsiveness remained for 4 days after the beginning of the culture. When it was bovine serum albumin, responsiveness lasted for about 8 days. Once an anamnestic response had begun, antibody formation continued for 4 weeks or more. High concentrations of bovine serum albumin (0.5 mg/ml) did not inhibit the response. When both antigens were used to stimulate the same culture, it was found that the two responses were independent.

The immune elimination of soluble BSA, following an intravenous injection, is accompanied by the appearance of circulating antigen-antibody complexes. The pattern of the appearance of circulating antigen-antibody complexes and the immune elimination of antigen probably depends on the amount of antigen injected, the rate of antibody synthesis, and perhaps, the quality of antibody produced. There is no relationship between the I* antigen-antibody complexes detected during the immune response in rabbits by ammonium sulfate precipitation and the material precipitated from immune sera as a result of treatment with alkali. Alkali-precipitable material present in the serum of rabbits at a time when I* antigen is also present contain at most only traces of the antigen.

Cell suspensions from the spleens of normal mice or mice injected with sheep erythrocytes were separated on a discontinous bovine serum albumin density gradient. Four bands or subpopulations were obtained and were assayed for antibody-forming cells, and for antigen-sensitive precursor cells. The antibody-forming cells were assayed by the hemolytic plaque assay and the antigen-sensitive precursors were assayed by the number of plaque-forming cells which developed after 3 or 5 day's culture with antigen. It was found that both antibody-forming cells and their precursors were present in the denser region of the gradient when spleen cell suspensions were taken from unimmunized mice. In contrast, both antibody-forming cells and precursors floated to the top in cell suspensions from mice sacrificed 1, 2, or 3 days after antigen injection. The change in density was detectable as early as 12 hr and was complete by 18 hr. The cell which changed in density was specific for the antigen that brought about that change. The significance of these findings is discussed.
