Abstrakt: Mice were immunized in vitro and in vivo against the tumor-associated antigens of a methylcholanthrene-induced tumor, with immunogen cells coupled to the p-nitrophenyl ester of N-acetylmuramyl- l-alanyl- d-isoglutamine (adjuvant peptide). Immune activity was measured either with a short-term chromium release assay or by following the regression of small tumors. Interposing a glycylglycylcystamide spacer between the adjuvant peptide and the tumor cell surface further increased tumor immunogenicity. Beige mice developed good anti-tumor immunity, whereas nude mice developed none. [ABSTRACT FROM AUTHOR]
