Receptors for immune complexes on cells within a non-lymphoid murine tumor.

In this paper we present evidence that antibodies unrelated to the tumor cell can comprise part of the in vivo Ig surface coat of cells derived from the non-lymphoid murine tumor, TA3/St. This was shown by incubating TA3 cells originating from other OA or BSA preimmunized mice with radioiodinated 125I-OA and 131I BSA. Radioiodine-labeled 125I-OA specifically fixed to cells derived from TA3/St tumors originating from OA-preimmunized mice.
