Omschrijving: Schoon drinkwater is van essentieel belang voor de gezondheid. In de darmen van zoogdieren en vogels kunnen zowel pathogene als onschadelijke bacteriën worden aangetroffen. Water testen op alle mogelijke typen pathogene bacteriën is een langzaam en duur proces. Daarom wordt water getest op een kenmerkend type darmbacterie - de coliformen - waartoe ook de bekende <i>E. coli</i> behoort. De aanwezigheid van coliformen is een indicatie voor fecale besmetting. In dit experiment testen leerlingen op coliformen in gesimuleerd verontreinigd water met behulp van kleurstoffen en fluorescente reagentia. Dezelfde reagentia kunnen worden gebruikt om watermonsters uit de omgeving te testen. Als extra activiteit kan er een Gram-kleuringstest worden uitgevoerd op de verzamelde monsters.

Omschrijving: Genetic modification of plants is a controversial area of biotechnology. All such experiments in plants begin with establishing plant cells in culture. This involves de-differentiating plant cells to form plant "stem cells". In this experiment, students establish cell cultures of African violets from leaves. They then use plant growth regulators to encourage root growth from the cultured cells, and produce a mature plant.

Omschrijving: 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.

Omschrijving: Met de Ready-to-Load™ PCR-kit kunnen leerlingen kennismaken met de principes en toepassingen van polymerasekettingreacties (Polymerase Chain Reaction, PCR). Dit simulatie-experiment bevat geen menselijk DNA en er is geen thermocycler voor nodig.

Omschrijving: When DNA is subcloned in the pUC polylinker region, β-galactosidase production is interrupted, resulting in the inability of cells to hydrolyse X-Gal. This results in the production of white colonies amongst a background of blue colonies. This experiment provides a DNA fragment together with a linear plasmid and T4 DNA ligase. Following the ligation to synthesis the recombinant plasmid, competent <i>E. coli</i> cells are transformed and the number of recombinant antibiotic-resistant white and blue colonies are counted. β-galactosidase activity is assayed from blue and white bacterial cells.

Omschrijving: 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.

Omschrijving: Met behulp van voorgekleurde LyphoProteins wordt de molecuulmassa van subunits bepaald door analyse met behulp van elektroforese op polyacrylamidegel met denaturerend SDS. Voorgekleurde proteïnen met onbekende molecuulmassa krijgen een molecuulmassa toegewezen op basis van de relatieve mobiliteit ten opzichte van voorgekleurde standaardproteïnemarkers.

Omschrijving: 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.

Omschrijving: Suppressor genes, such as p53, are essential for cell functions. Mutations in the p53 gene can be correlated to predisposition for certain cancers. Mutations of genes can either be inherited or accumulated due to environmental insults. This experiment deals with a family pedigree determination of several generations relating to cancer formation due to p53 gene mutation.

Omschrijving: ABO and Rh typing of blood left at the scene of a crime can help to narrow down a list of suspects. In this experiment, students use agglutination to identify the blood group of unknown blood samples as a step to identify a criminal.

Omschrijving: Drinking water is routinely tested for contamination. If a screening tests positive, more sophisticated tests are required. One such test uses PCR in multiplex format. In this experiment, students test for the presence of three separate, classroom-safe organisms in a water sample using a single PCR reaction.

Omschrijving: This experiment introduces a simple method to determine protein subunit molecular weights using horizontal electrophoresis. As the protein standards and 'unknowns' are prestained, the separation of proteins can be observed during electrophoresis. Included in the experiment is protein-grade agarose, which provides an alternative to the use of polyacrylamide gels.
