Beskrivelse: The Hydrophobic Chromatography kit is designed to teach students the basic principle of hydrophobic chromatography utilising a hydrophobic enzyme. The use of the enzyme allows purification followed by a simple enzyme assay to detect the fractions that contain the enzyme. This lab activity involves preparation of a crude protein extract and running hydrophobic chromatography to isolate the enzyme.

Beskrivelse: 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.

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.

Beskrivelse: With the equipment, centrifugal forces that arise during a body's rotation around a specific axis can be measured and examined. The device consists of a plane with a path for a cart. On the underside there is a vertical shaft that is mounted in a bearing. The plane is made to rotate with a laboratory motor connected with a drive belt to the bearing. The experimental trolley is placed on the track and prevented from leaving the track by two bent steel wires. A wire is connected to the trolley that runs over a pulley and on to a dynamometer.

Beskrivelse: In this experiment, transformed cells take up a plasmid containing the Green Fluorescent Protein (GFP) gene. The GFP gene was isolated from the jellyfish <i>Aequorea victoria</i>. Transformed colonies expressing the GFP protein are visibly green in normal light but will fluoresce brightly when exposed to longwave UV light.

Beskrivelse: This experiment introduces a simple method to determine protein subunit molecular weights using horizontal electrophoresis. As the protein standards and 'unknowns' are prestained, the separation of proteins can be observed during electrophoresis. Included in the experiment is protein-grade agarose, which provides an alternative to the use of polyacrylamide gels.
