SYBR® Safe Stain is a DNA stain that fluoresces with a bright green colour when excited with UV light. Like ethidium bromide, SYBR® Safe Stain binds specifically to the DNA double helix.

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 E. coli 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.

Genetic modification of plants is a controversial area of biotechnology. All such experiments in plants begin with establishing plant cells in culture. This involves de-differentiating plant cells to form plant 'stem cells'. In this experiment, students establish cell cultures of African violets from leaves. They then use plant growth regulators to encourage root growth from the cultured cells, and produce a mature plant.

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

Students use primers for a 300 base pair Alu insertion in chromosome 16 (PV92) to determine their own genotype. They can then compare their class results with others around the world over the internet.

Ready-to-Load™ PCR kit introduces students to the principles and applications of the Polymerase Chain Reaction (PCR). This simulation experiment does not contain human DNA and does not require a thermal cycler.

Observe the differences between mammalian cell types and how these cells funciton. Cells are fixed on microscope slides and students stain the cells on the slide to view morphological characteristics of the cell types. These cells are very safe for classroom use.

ABO and Rh typing of blood left at the scene of a crime can help to narrow down a list of suspects. In this experiment, students use agglutination to identify the blood group of unknown blood samples as a step to identify a criminal.

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.

Using prestained LyphoProteins, subunit molecular weights are determined by analysis using denaturing SDS vertical polyacrylamide gel electrophoresis. Prestained proteins with unknown molecular weights are assigned molecular weights based on the relative mobility of prestained standard protein markers.
