Cellular localization of immunoglobulin within human maglignant melanomata.
The presence of antibody in patients with malignant melanoma is well established if one examines the serum. In this report we have attempted to identify antibody within solid tumours showing that they are rarely present in any appreciable quantity on the surface of tumour cells but can be seen frequently on a number of different types of host cell within the tumours. This is discussed in the light of the role of antibody in the circulation and the possibility of antibody behaving as a blocking factor in vivo.
