ABSTRACT:
A composition for the upregulation of expression of cell antigens, without inducing shedding, which comprises a protein kinase C activator is provided by this invention. Further provided by this invention is a method of detecting and treating tumor cells comprising contacting tumor cells with an effective amount of a protein kinase C activator for the upregulation of expression of antigens of tumor cells, without inducing antigen shedding, and detecting the presence of said antigen or then further contacting said tumor cells with an effective amount of an antibody directed to said antigen.
