Genetic testing can be used to identify people with a genetic condition which caused them to have an elevated level of cholesterol and which can be fatal. Students can see how genetic testing is carried out and learn about DNA electrophoresis.

In this PCR experiment, students make billions of copies of a small amount of DNA in only 90 minutes. They just need to mix template DNA and primers with PCR beads that contain all of the other components required to carry out a PCR reaction. Students see the increasing amounts of DNA for themselves, taking samples every few cycles and analysing them on a DNA gel.

Supplier: EDVOTEK

In DNA fingerprinting, variable number tandem repeats (VNTR) are used to identify individuals. Using this kit, students type themselves at the D1S80 locus on chromosome 1. This region contains between 14 and 40 copies of a 16 base pair repeat.

Learn the basics of DNA sequencing and sequence homology with this lab activity.

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.

Supplier: EDVOTEK

For learning about the diversity of proteins by studying the electrophoretic profiles of various sources. Students separate proteins from bacterial, plant, serum, and milk proteins alongside a standard protein marker.

Supplier: EDVOTEK

Plasmid and lambda DNA are pre-digested with restriction endonucleases that recognise and cut double-stranded DNA within or near defined base sequences. Digests are separated by agarose gel electrophoresis.

Supplier: EDVOTEK

The DNA from bacteriophage Lambda is a well-characterised linear molecule containing six recognition sites for Eco RI (5 distinct sites, 2 are very close in size). In this experiment, Lambda DNA is digested by the Eco RI endonuclease. The digestion products are analysed by agarose gel electrophoresis.

This easy and safe experiment allows students to learn about enzyme catalysis, the nature of enzyme action, and protein structure-function relationship. Students will perform an enzyme assay and determine the rate of the enzymatic reaction.

Supplier: EDVOTEK

Small-scale, rapid isolation of plasmid DNA is a routine procedure used for screening and analysis of recombinant DNAs in cloning and sub-cloning experiments. In this experiment, students isolate plasmid DNA without the use of toxic chemicals such as phenol or chloroform.

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.

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.

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.

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.

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.
