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.

FLUOR DE LYS® Developer II is an essential reagent for signal generation in assays done with the FLUOR DE LYS®-HDAC8, FLUOR DE LYS®-SIRT1 and FLUOR DE LYS®-SIRT2 substrates. Deacetylation of the FLUOR DE LYS® substrate sensitises it so that, in a second step, treatment with the FLUOR DE LYS® Developer II produces a fluorophore. Typically, an ‘inhibitor stop’ will be included in the 1X Developer dilution (e.g. nicotinamide for sirtuins).

FLUOR DE LYS® Developer is an essential reagent for signal generation in HDAC or sirtuin assays done with the FLUOR DE LYS® substrate. An appropriate FLUOR DE LYS® family substrate, comprising an acetylated lysine side chain, is first incubated with a sample containing HDAC activity (nuclear or cellular extract, purified enzyme, bead-bound immunocomplex, etc.). Deacetylation of the substrate sensitizes it so that, in a second step, treatment with the FLUOR DE LYS® Developer produces a fluorophore. Typically, an ‘inhibitor stop’ will be included in the 1x Developer dilution (e.g. Trichostatin A) for class I and II HDACs, nicotinamide for sirtuins).

Dialysis is a routinely used technique in research laboratories to 'change' the solution a biomolecule is dissolved in. Often the buffers used to isolate biomolecules, such as proteins, are not compatible with downstream applications due to high concentrations of reagents, such as salts. A sample is placed in a bag with a semi-permeable membrane and then placed in the new solution or water. Small molecules, such as salt, can pass through the membrane, moving from an area of high concentration to low concentration. The larger molecules, such as proteins, are retained in the bag. Microdialysis is a modification of dialysis to overcome the problem of dialysing small volumes of precious samples. Microdialysis uses small devices designed for small volumes. This kit allows students to study dialysis using patented microdialysis devices.

This lab activity involves analysis of an enzyme reaction using a specific enzyme substrate and inhibitor. Students study how the rate of enzyme reaction is dependent on substrate concentration and the influence of agents (inhibitors) and conditions that affects the enzyme reaction such as pH and temperature.

Bacterial conjugation is a naturally occurring process that allows the transfer of DNA from one bacterium to another, which allows the transfer of genetic traits, particularly drug resistance. The kit contains two bacteria with different drug resistance genes and all the tools for students to study bacterial conjugation. This kit teaches the difference between bacterial genomic DNA and the transferable plasmid DNA and the mechanisms of bacterial conjugation. Students will also learn important basic microbiological techniques, including bacterial growth in liquid broth and on solid agar plates, antibiotic selection of bacteria and important aseptic techniques.

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.
