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.

Infectious agents such as bacteria and viruses can spread rapidly through a population and cause widespready disease and death. In this experiment, students use coloured solutions to simulate the spreading of a disease in the classroom.

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.

Students learn the basic principles of the Enzyme-linked Immunosorbent Assay (ELISA) using this precise and sensitive antibody-based detection kit.

Kankercellen verschillen van normale cellen in de combinaties van proteïnen die aanwezig zijn op het oppervlak. Antilichamen tegen deze proteïnen binden zich specifiek aan kankercellen en niet aan normale cellen. Hierdoor kan kanker in een vroeg stadium worden ontdekt, en wordt een mogelijke methode gecreëerd voor het toedienen van kankertherapieën. In dit simulatie-experiment worden de reactie van kankercelmarkers en de bijbehorende antigenen gedemonstreerd.

Het lichaam verdedigt zichzelf tegen aanvallen van infectieuze micro-organismen, zoals bacteriën en virussen, door antilichamen te produceren. Met ELISA-tests (Enzyme Linked Immunosorbent Assays) kan worden onderzocht of er antilichamen aanwezig zijn in het bloed, wat een indicatie is voor een infectie. In dit experiment voeren leerlingen een gesimuleerde ELISA-test uit om geïnfecteerde monsters te identificeren en te vergelijken met controlemonsters.

De tweede assay die wordt gebruikt om een positief HIV ELISA-resultaat te bevestigen, is western blotting. Met behulp van deze kit kunnen leerlingen proteïnemonsters van hypothetische patiënten scheiden op agarosegels. De proteïnen worden vervolgens overgebracht op een membraan en gesimuleerde HIV-proteïnen worden gedetecteerd.

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.

Wanneer normale cellen op kweek worden gezet, stoppen ze met groeien wanneer er geen ruimte meer is (contactinhibitie). Kankercellen op kweek groeien ongecontroleerd omdat zij deze eigenschap niet meer hebben. Hierdoor kunnen er tumoren worden gevormd in het lichaam. Ook kunnen er vele verschillende celtypen aanwezig zijn in één enkele tumor. Met dit experiment kunnen leerlingen de verschillen in groei en celtype tussen normale cellen en kankercellen zien.

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.

This experiment introduces students to Southern blotting as a tool for DNA fingerprinting in a hypothetical paternity determination. DNA fragments are first separated by agarose gel electrophoresis, then transferred to a nylon membrane and finally visualised by staining.

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.

Bestudeer de verschillen tussen zoogdierceltypen en hoe deze cellen functioneren. De cellen zijn aangebracht op microscoopglaasjes en leerlingen kleuren de cellen op het objectglaasje om de morfologische kenmerken van de celtypen te kunnen bekijken. Deze cellen zijn zeer veilig voor gebruik in het klaslokaal.

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.

Over 30% of the world's population uses tobacco products, and 90% of that is from cigarettes. The physical effects of nicotine and the diseases it can cause, including cancer, are detailed on this anatomical poster. For such a wide spread practice education is important and this anatomy poster can help do that. This thickly laminated anatomical chart is printed on premium glossy (200 g) UV resistant paper and comes with two sided lamination (125 µm, 5,0 mil) and metal eyelets to make the chart easy to display.
