  3. TV or real life? The Walking Dead show Feb 11,2014 Atlanta

  4. Zombiefication • Method of infection • Bodily fluid contact • Airborne • Foodborne • Symptoms • Undead • Hungry for flesh • Treatment • None known

  5. Introduction to Immunology, Antibodies and ELISA • Fluid swapping and disease spreading! • Indirect ELISA to narrow down who were the initial carriers of the disease

  6. Crash Course in Immunology and ELISA Immune Response C. Macrophage A. Pathogen Zombie virus D. Macrophage B. B cells F. T cell E. Macrophage G. B cell J. Antibodies attach to pathogen Antibodies are ineffective Against Zombie Virus H. Memory B cells I. Plasma cells

  7. Heavy chain Disulfide bonds Light chain Crash Course in Immunology and ELISA Antibody Structure ELISA tests are based on immune system antibody molecules Antigens

  8. ELISAEnzyme-Linked Immunosorbant Assay (indirect) Add the purified antigen to all the wells. Incubate for 5 min. Rinse Add serum antibodies (student samples) to the appropriate wells. Incubate for 5 min. Rinse Add the enzyme-linked antibody to all wells. Incubate for 5 min. Rinse Add enzyme substrate to all wells. Incubate for 5 min.

  9. Swapping Fluids and Disease Swap with 1 person at your table (record who) Add your 750 µl together, mix and each take 750 µl back

  10. Swapping Fluids and Disease Swap with 1 person at the closest table (record who) Add your 750 µl together, mix and each take 750 µl back

  11. Swapping Fluids and Disease Swap with 1 person at the another table (record who) Add your 750 µl together, mix and each take 750 µl back
