These four orphans are trying to find their blood brothers or sisters from whom they were separated while very young.  Is it possible that they are related?  Students visualize antigen-antibody agglutination reactions as they learn the genetics, immunology, and medical implications of blood typing in the context of this fun and totally safe simulated activity. Includes a complete 16 page instructor’s manual, 72 reusable glass microscope slides, 50 Hema-tags® for recording lab results, mixing picks, and 15 ml bottles simulated antisera and blood regents. Designed for multiple reuses.
