Descrizione: This lab activity is designed to demonstrate the different classes of protein molecules and their classification based on solubility. Students learn fractionation of soluble, insoluble membrane proteins, and cytoskeleton proteins from a tissue sample. The insoluble protein fraction is further fractionated into hydrophilic and hydrophobic membrane proteins. Cell membrane structure and the role of hydrophobic membrane proteins are considered. This lab activity also provides an opportunity to understand characteristics of various classes of detergents and the role of detergents in solubilisation of hydrophobic membrane proteins.

Descrizione: The physical properties of proteins kit is a lab activity that enables students to investigate the physical properties of several different proteins. Students will learn about protein solubility and how it is affected by various parameters; including temperature, pH, salt and dielectric constant. They will understand about protein precipitation due to pH, high salt and in the presence of organic solvents and about protein denaturation as a result of high temperature. In addition, the kit will demonstrate how non-protein agents, such as detergents drastically alter the physical properties of protein molecules and as a result, understand the importance of detergents in protein solubilisation. This lab activity involves analysis of three different types of pure proteins and then students alter some of those properties with a detergent and re-examine physical properties of those proteins. Students are challenged to consider how physical properties of protein molecules can be exploited for purification and characterisation of proteins and apply their findings on a test sample of complex tissue extract.

Descrizione: 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.

Descrizione: 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.

Descrizione: 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.

Descrizione: 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.

Descrizione: 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.
