Video of three experiments: serum antibody / antigen complex formation, hemagglutination, and cytolysis. These videos are representative demonstrations of a series of tests conducted on the blood of a person with a known allergy to tree nuts. Tests were performed using various extracts of nuts, drupes, and fruits. Results were provided to the test subject (and principle investigator) for amusement only!
