Beskrivelse: 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.

Beskrivelse: 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.

Beskrivelse: 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.

Beskrivelse: The three most frequently used restriction enzymes are Eco RI, Bam HI and Hind III. Each enzyme catalyses cleavage at the defined base sequence. All enzymes are lyophilised and contain 1500 units. One unit is defined as the amount of enzyme required to digest 1,0 µg of lambda DNA in 60 minutes at 37 °C in a total reaction mixture of 50 µl.

Beskrivelse: Using the Protein Electrophoresis kit, students will learn the principles of various types of electrophoresis, including denaturing and non-denaturing electrophoresis, and how this powerful technique is used to analyse proteins. The kit will introduce students to the different separation matrices currently in use and will understand their differing separation properties and their role in protein analysis. Students have an option of casting their own electrophoresis gels using polyacrylamide or using pre-cast commercially available gels. This kit is provided with all of the reagents, buffers and supplies needed for casting acrylamide gels, preparing protein samples, running electrophoresis, and staining the gels for visualisation of protein bands. Test protein samples and protein standards are also provided.

Leverandør: G-Biosciences

Beskrivelse: In this lab activity, students learn to perform carefully controlled experiments to generate protein fragments using a proteolysis enzyme and then analyse the protein fragments by electrophoresis. By analysis of protein fragmentation patterns, i.e. protein fingerprints, students learn about protein sequence, structure, and their conservation. Students resolve a set of three functionally identical protein samples selected from throughout the animal kingdom; including human, bovine and sheep. After generating fingerprints by electrophoresis, students examine the protein fingerprint of each sample to determine the degree of conservation.
