Heterologous antibodies in human and rat's glioblastoma.
IgG from immunized rabbits was labelled with Fluorescein Isothiocyanate, and conjugated in vitro with human and with rat glioblastoma. After absorption of the antisera with normal brain and liver, a heavy concentration of antibody was found in the rat tumour cells. A great amount of antibody was also found in the human neoplastic cells. The incorporation of this antibody in glioma cells of different rats developing new tumours indicates that transplantation antigens of the H-2 type are not the only ones capable of inducing specific antibody attachment.
