For over 50 years, immunoassays have been used by physicians, biologists, and forensic scientists to diagnose disease, detect contamination, and to determine the origin of biological samples found at crime scenes. Immunoassays rely on the uniqueness of antibodies. Antibodies are typically produced by the immune system in response to antigens – bacteria, viruses, pollen, or anything that your body perceives as foreign. Our bodies are capable of producing billions of different protective proteins called antibodies, each one specific to a different antigen. When an antibody and an antigen are a match, they bind together – similar to a lock and key. Scientists are able to produce and purify antibodies – often from animals – that then can be used to test for many different things.
The purpose of this activity is to develop student interest, knowledge, and skills in the areas of biotechnology and life sciences. It engages students with a hands-on activity that is fun, interesting, and informative. Join us as we explore a scientific explanation to what’s lurking in the lake.
