▎ 摘　　要

NOVELTY - Preparing an whole-target antigen presenting cell tumor vaccine comprises co-incubating a quantum dot modified tumor cell and an immature antigen presenting cell, where the quantum dot modified tumor cell is obtained by connecting a quantum dot with a protein molecular chain of a tumor cell by using a hydrogen bond in a ligand manner. USE - The whole-target antigen presenting cell tumor vaccine is useful in preparing medicine for treating or preventing tumor, preferably lung cancer cells, breast cancer cells, ovarian cancer cells, renal cancer cells, nasopharyngeal carcinoma cells, esophageal cancer cells, colorectal cancer cells, malignant glioma cells, and epithelial cell-derived malignant cells of brain myeloma cells (all claimed). ADVANTAGE - The vaccine enhances the uptake of the tumor antigen and increases the major histocompatibility complex (MHC) molecule expression on a large scale and improves the antigen presenting efficiency, and is prepared by simple process and economical. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for whole-target antigen presenting cell tumor vaccine prepared by above method.
