Experimentation kits, simulation of HIV detection by western blot (agarose-based)
Supplier: EDVOTEK
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.

Experimentation kits, what is an epidemic and how does an infection spread?
Supplier: EDVOTEK
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.

Experimentation kits, southern blot analysis
Supplier: EDVOTEK
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.

Experimentation kits, DNA damage and repair
Supplier: EDVOTEK
According to the World Health Organisation, between two and three 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.

Experimentation kits, blood-based cancer diagnostics
Supplier: EDVOTEK
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.

Experimentation kits, how does a doctor test for AIDS?
Supplier: EDVOTEK
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.

Experimentation kits, in search of the 'Kissing Disease'
Supplier: EDVOTEK
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.

Experimentation kits, analysis and comparision of mammalian cell types
Supplier: EDVOTEK
Observe the differences between mammalian cell types and how these cells funciton. Cells are fixed on microscope slides and students stain the cells on the slide to view morphological characteristics of the cell types. These cells are very safe for classroom use.

Experimentation kits, antigen-antibody interaction: the ouchterlony procedure
Supplier: EDVOTEK
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.

Experimentation kits, detection of a simulated infectious agent
Supplier: EDVOTEK
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.

Experimentation kits, morphology of cancer cells
Supplier: EDVOTEK
When normal cells are grown in culture they stop growing when they become overcrowded (contact inhibition). Cancer cells in culture grow in an uncontrolled way because they have lost this property. This helps tumours to form in the body. In addition, many different cell types can be present in a single tumour. This experiment allows students to see the differences between normal and cancer cells in both their growth and cell types.

Experimentation kits, simulation of HIV detection by ELISA
Supplier: EDVOTEK
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.

Experimentation kits, antigen-antibody interactions
Supplier: G-Biosciences
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.

Nicotine dependence chart
Supplier: 3B Scientific
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.
