Globo-H-PrNH2 is primarily used in the field of immunotherapy, particularly in cancer vaccine development. It serves as a synthetic antigen that mimics specific carbohydrate structures found on the surface of cancer cells. This makes it valuable for stimulating the immune system to recognize and attack cancer cells more effectively. Researchers utilize it to create targeted therapies, especially for cancers like breast, ovarian, and prostate cancer, where these carbohydrate structures are overexpressed. Additionally, it plays a role in antibody production and is studied for its potential in improving the specificity and efficacy of cancer treatments.
