by immunoelectrophoretic and immunodiffusion analyses of specifically purified antibody , and antibody non-specifically fractionated by column chromatography and ultracentrifugation , it was established that there was no demonstrable igm antibody , that most of the antibody appeared to be igg , and that a gamma1 immunoglobulin , probably iga or t-globulin , may have been responsible for some of the activity .
