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.

The standard anionic surfactant method has several drawbacks:
*Multiple handling steps are time consuming and complicated.
*Large volumes of extraction solvents create a safety and environmental risk.
*The combination of lengthy handling time, glassware maintenance, and solvent disposal adds up to significant costs per test. A standardised cuvette-based extraction and photometric measurement system overcomes all these disadvantages to provide accurate, reproducible results.

The Gram staining method was first described in 1844 by the Danish bacteriologist Hans Christian Gram, after whom the test was named. The Gram staining test for bacteria is one of the most important tests in microbiology and is often one of the first tests performed in the identification of bacteria. The Gram staining method utilises the properties of bacterial cell walls and the stain crystal violet. Gram-positive microorganisms have a higher peptidoglycan and lower lipid content than Gram-negative bacteria in their cell walls and this makes them capable of retaining the Gram stain. This kit is supplied with two strains of bacteria and all the necessary components to carry out the Gram staining.

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.

Biodiversity lab activity is designed for determination of protein contents and biomass in diverse biological samples to study how biomass is related to biodiversity in nature. Students collect and catalogue plant leaf samples from a diverse group of locally available plants. This lab activity involves determination of natural weight of each plant sample, grinding a predetermined amount of each sample, and the subsequent extraction of proteins from the samples. Students then learn to determine protein contents of each plant sample and attempt to relate the protein content with biomass. Students in this lab activity are challenged to think, analyse, and seek answers as to why protein biomasses vary for a given natural weight for different plants. Finally, they will relate that finding to the biodiversity of nature.

Safe drinking water is vitally important to health. Both pathogenic and harmless bacteria can be found in the guts of mammals and birds. Testing water for every possible type of pathogenic bacteria is slow and costly. Thus, water is tested for a characteristic type of gut bacteria - the coliforms - including the familiar E. coli. Presence of coliforms is an indicator for faecal contamination. In this experiment, students test for coliforms in simulated contaminated water using colour and fluorescent reagents. They can use these same reagents to test water samples from the environment. As an extension activity, a Gram Stain test can be performed on the collected samples.

These Chemiluminescent Western Blot Kits allow for the detection of primary polyclonal or monoclonal antibodies provided by the user. After protein separation and transfer, the membrane is probed with primary antibody. Detection of the membrane-bound primary antibody-antigen complex is achieved by the addition of a secondary antibody conjugated to the enzyme horseradish peroxidase. The enzyme reacts with a specialised formulation of luminol, an extremely sensitive, non radioactive substrate that emits light and allows visualisation using X-ray film or other imaging methods, including highly sensitive CCD cameras and imaging systems. Because of the extremely high sensitivity of the kit, primary and secondary antibodies can be used at greater dilutions. Primary antibodies currently diluted 1:1000 using an ECL™ substrate is the equivalent of a 1:5000 dilution using the FemtoMax™ substrate.
