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: In this experiment, students see a blue colour change in transformed cells due to the switching on of a gene. The pGAL plasmid gives a blue colour dye due to the production of the β-galactosidase protein by the <i>lacZ</i> gene. IPTG is not required in this experiment since pGAL contains the complete <i>lacZ</i> gene.

Omschrijving: Microarray technology allows scientists to screen large numbers of samples in one assay. This technology allows high-throughput screening of small samples and allows comparisons to be made between healthy and unhealthy tissues. In this experiment, students apply simulated DNA and RNA samples to a membrane to screen for positive and negative samples.

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: 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.

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

Omschrijving: Following restriction enzyme digestion of DNA molecules, researchers need to rejoin the ends of the DNA to generate recombinant DNA, a process known as ligation. Ligation of DNA is achieved with the bacterial enzyme T4 DNA ligase, which catalyses the formation of phosphodiester bonds. The DNA Ligation kit teaches students about ligation as they ligate several DNA fragments together to make larger pieces of DNA that are easily identified by agarose electrophoresis.

Omschrijving: The Size Exclusion Chromatography kit teaches gel filtration or size exclusion chromatography and the use of this method in purification of biological samples. This method is based on separation of protein molecules based on their molecular size. This lab activity involves running size exclusion chromatography for separation of molecules based on their molecular sizes.

Omschrijving: Most molecules have a net charge within a pH range of 2 to 10. When the pH is altered, the net charge on molecules can change drastically. In this experiment, a mixture of two chemicals is absorbed onto a solid support ion-exchange column and separated during elution under conditions that influence their net charge.
