Abstract
The tumor-associated mucin MUC1 is overexpressed in almost all types of epithelial tumor tissues, making it an attractive target antigen for cancer immunotherapy. Here we present a protocol to prepare MUC1 glycopeptide vaccines and to evaluate immunization effects in mice. We describe steps for synthesizing glycopeptide antigen and conjugating it with carrier protein to make vaccine candidates. We then detail procedures for mice immunization, antibody response evaluation, and cellular immune response. For complete details on the use and execution of this protocol, please refer to Cai et al.1,2.
