This test tube contains a solution with antibodies from mice that neutralise the CTLA-4 protein. James Allison discovered that the antibody can make the immune system more responsive so it can neutralise cancer tumours. After the discovery, a corresponding antibody was found in humans. Based on the results, a pharmaceutical could then be developed to treat some types of cancer. The vial contains this drug.
James Allison donated the test tube and the vial to the Nobel Prize Museum in 2018.
