Beskrivelse: Cancer cells differ from normal cells by the combinations of proteins that are present on their surfaces. Antibodies against these proteins will specifically bind to cancer cells and not to normal cells. This allows early detection of cancer and potentially a way of delivering cancer therapies. In this simulation experiment the reaction of cancer cell markers and their corresponding antigens are demonstrated.

Beskrivelse: The body defends itself from attack by infectious agents like bacteria and viruses by producing antibodies. Enzyme linked immunosorbent assays (ELISA) test for antibodies present in the blood, which indicate infection. In this experiment, students perform a simulated ELISA test to identify infected samples and compare them to control samples.

Beskrivelse: According to the World Health Organisation, between 2 and 3 million cases of skin cancer occur globally every year. Many of these cases are caused by preventable damage to DNA by UV light. In this experiment, students expose plasmid DNA to shortwave UV light to simulate the effect of sunbathing. The DNA is then analysed by agarose gel electrophoresis to observe the damage.

Beskrivelse: Når normale celler dyrkes i kultur, slutter de å vokse når de blir overfylte (kontakthemming). Kreftceller i kultur vokser på en ukontrollert måte fordi de har mistet denne egenskapen. Dette hjelper til med å danne svulster i kroppen. I tillegg kan mange forskjellige celletyper være tilstede i en enkelt svulst. Dette eksperimentet lar elevene se forskjellene mellom normale celler og kreftceller i både vekst og celletyper.

Beskrivelse: The second assay used to confirm a positive HIV ELISA result is the Western blot. Using this kit, students separate protein samples from hypothetical patients on agarose gels. The proteins are then transferred to a membrane and simulated HIV proteins are detected.

Beskrivelse: An infectious outbreak requires prompt and accurate identification of the biological agent. Often, early clinical symptoms are first identified in exposed individuals and then infectious agents are identified by lab tests. In this experiment, students transmit a simulated infectious agent (chemical dye) between classmates which is only visible under long UV light. The pattern of transmission and primary source is documented.

Beskrivelse: Infectious mononucleosis is commonly known as the 'kissing disease'. The causative agent is Epstein-Barr virus (EBV), which can be transmitted through saliva during kissing. In this experiment, students search for the presence of EBV using the ELISA reaction to detect specific viral proteins.

Beskrivelse: This experiment introduces students to the principles of antigen-antibody interactions by using the Ouchterlony procedure. Antibodies and antigens form complexes that precipitate, making it possible to assay antibody-antigen systems. The binding interaction results in the formation of a white precipitate after diffusion in agarose.

Beskrivelse: An HIV test detects HIV infection indirectly using an ELISA test against HIV antibodies in the blood. The test works by taking antibodies from the patient's blood and adding them to a microtitre plate coated with HIV antigen. If HIV antibodies are present, they will bind to the antigens on the plate. In this experiment, students perform an ELISA text by coating microtitre plate wells with simulated HIV antigen and then test simulated donor serum for anti-HIV antibodies.

Beskrivelse: This lab activity is designed to study highly specific lock-key matching properties of antigen-antibody and how this highly specific interaction can be exploited as a tool for research and analysis. This study involves the use of an immunodiffusion technique in which antigen and antibody are allowed to diffuse in a solid agarose medium. When antigen and antibody meet, antigen-antibody complex is formed, which leads to precipitation. Antigen-antibody precipitate is formed in the zone where the concentration of the two matching pairs reaches an optimal known as the zone of equivalence, which results in formation of a visible opaque precipitate region in agarose medium. Those regions of precipitation can be used for determination of concentration or titer of both antigen and antibody. This Antigen-Antibody Interaction kit is a hands-on study of both Ouchterlony Double Diffusion and Radial Immunodiffusion techniques. This kit also provides additional guidance materials for teaching other types of antigen-antibody interactions concepts such as immunoelectrophoresis and immunoprecipitation.
