Beskrivelse: Oil spills cause devastation to the environment, killing sea life, birds, and coastal plants. Spraying areas of contamination with oil-eating microbes accelerates the degradation of the oil. This process is known as bioremediation. In this open-ended experiment, students grow a mixture of oil-eating bacteria and observe their effectiveness at degrading a variety of oils.

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: 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.

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: The Green Fluorescent Protein (GFP) from the jellyfish <i>Aequorea victoria</i> is used extensively in all areas of science. Many organisms have been transformed with the GFP gene, the gene responsible for bioluminescence in jellyfish. It has proven to be so useful that scientists have mutated it to produce Blue Fluorescent Protein (BFP). In this simple experiment, students transform bacteria either by GFP, BFP or both.

Leverandør: EDVOTEK

Beskrivelse: Four experimental modules are combined into one experiment to provide a comprehensive biotechnology exploration focusing on the green fluorescent protein (GFP). Bacterial cells are transformed to express the GFP. The transformed cells are then grown and the GFP purified by column chromatography. Finally, the purity of the protein fractions are analysed by SDS polyacrylamide electrophoresis.

Beskrivelse: When bacteria are used to make medicinally useful proteins by transformation, the protein of interest must be separated from all of the other cellular proteins. In this experiment, the unique fluorescent properties of GFP and BFP are used as an assay during their purification from an <i>E. coli</i> extract. The column fractions containing GFP or BFP are identified by fluorescence and then purified. As an optional activity, purified protein fractions can be separated by SDS polyacrylamide gel electrophoresis (SDS-PAGE) to estimate the purity and size of the GFP and BFP proteins.

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: Evidence left behind at a crime scene can identify a potential culprit. Even in this age of DNA, fingerprints and blood stains are still important in helping to identify a criminal. In this experiment, students solve a crime by dusting for fingerprints and use fluorescent dust to search for and identify trace amounts of blood.
