The Edvotek White Light Box features a spacious 25×25 cm viewing area illuminated by long life LEDs and is housed in a slim aluminium body. It is designed to safely enhance the visualisation of DNA stained with FlashBlue™, proteins stained with Coomassie Blue and autoradiograms.

Supplier: EDVOTEK

The TruBlu™ blue light transilluminator is ideal for viewing DNA gels stained with SYBR® Safe, thus eliminating the need for UV light or ethidium bromide. It is optimised to fit Edvotek® gels as well as any other agarose gels.

Supplier: EDVOTEK

In this experiment, total protein extracts from several bacterial sources are extracted and compared. The unique patterns of protein bands, obtained by SDS vertical polyacrylamide electrophoresis, can be used to identify various bacterial strains.

Supplier: EDVOTEK

Water baths incorporating digital temperature control and an optional shaking capacity (10 L model only).

Supplier: EDVOTEK

Capable of running one or two groups of student samples at the same time and producing excellent results in 30 to 40 minutes.

Oil spills cause devastation to the environment, killing sea life, birds, and coastal plants. Spraying areas of contamination with oil-eating microbes accelerates the degradation of the oil. This process is known as bioremediation. In this open-ended experiment, students grow a mixture of oil-eating bacteria and observe their effectiveness at degrading a variety of oils.

When bacteria are used to make medicinally useful proteins by transformation, the protein of interest must be separated from all of the other cellular proteins. In this experiment, the unique fluorescent properties of GFP and BFP are used as an assay during their purification from an E. coli extract. The column fractions containing GFP or BFP are identified by fluorescence and then purified. As an optional activity, purified protein fractions can be separated by SDS polyacrylamide gel electrophoresis (SDS-PAGE) to estimate the purity and size of the GFP and BFP proteins.

Cancer cells differ from normal cells by the combinations of proteins that are present on their surfaces. Antibodies against these proteins will specifically bind to cancer cells and not to normal cells. This allows early detection of cancer and potentially a way of delivering cancer therapies. In this simulation experiment the reaction of cancer cell markers and their corresponding antigens are demonstrated.

Electrophoresis Gels, UltraSpec-Agarose™

Supplier: EDVOTEK

Four experimental modules are combined into one experiment to provide a comprehensive biotechnology exploration focusing on the green fluorescent protein (GFP). Bacterial cells are transformed to express the GFP. The transformed cells are then grown and the GFP purified by column chromatography. Finally, the purity of the protein fractions are analysed by SDS polyacrylamide electrophoresis.

According to the World Health Organisation, between two and three million cases of skin cancer occur globally every year. Many of these cases are caused by preventable damage to DNA by UV light. In this experiment, students expose plasmid DNA to shortwave UV light to simulate the effect of sunbathing. The DNA is then analysed by agarose gel electrophoresis to observe the damage.

The body defends itself from attack by infectious agents like bacteria and viruses by producing antibodies. Enzyme linked immunosorbent assays (ELISA) test for antibodies present in the blood, which indicate infection. In this experiment, students perform a simulated ELISA test to identify infected samples and compare them to control samples.

Supplier: EDVOTEK

This experiment uses PCR to amplify a small section of Lambda DNA via a 2-step process, saving valuable classroom time and allowing completion of the lab in one session.

The Green Fluorescent Protein (GFP) from the jellyfish Aequorea victoria is used extensively in all areas of science. Many organisms have been transformed with the GFP gene, the gene responsible for bioluminescence in jellyfish. It has proven to be so useful that scientists have mutated it to produce Blue Fluorescent Protein (BFP). In this simple experiment, students transform bacteria either by GFP, BFP or both.

FlashBlue™ is a DNA stain that offers simple and rapid staining of agarose gels.

Supplier: EDVOTEK

When normal cells are grown in culture they stop growing when they become overcrowded (contact inhibition). Cancer cells in culture grow in an uncontrolled way because they have lost this property. This helps tumours to form in the body. In addition, many different cell types can be present in a single tumour. This experiment allows students to see the differences between normal and cancer cells in both their growth and cell types.

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.

Southern blotting is an important technique used widely in clinical genetics and research. By transferring DNA from an agarose gel onto a membrane the method allows the precise analysis and identification of DNA bands on a gel. Using this kit, students use Southern blotting to find a point mutation in the haemoglobin gene indicating Sickle Cell Anaemia.
