Microarray technology allows scientists to screen large numbers of samples in one assay. This technology allows high-throughput screening of small samples and allows comparisons to be made between healthy and unhealthy tissues. In this experiment, students apply simulated DNA and RNA samples to a membrane to screen for positive and negative samples.

Isolation of high molecular weight chromosomal DNA is the first step in molecular cloning since it is the source of genes in cells. This experiment provides DNA extraction LyphoCells and reagents for isolating chromosomal DNA from E. coli. After spooling from solution, the DNA can be dissolved and analysed by agarose gel electrophoresis as an optional lab extension activity.

The three most frequently used restriction enzymes are Eco RI, Bam HI and Hind III. Each enzyme catalyses cleavage at the defined base sequence. All enzymes are lyophilised and contain 1500 units. One unit is defined as the amount of enzyme required to digest 1,0 µg of lambda DNA in 60 minutes at 37 °C in a total reaction mixture of 50 µl.

An infectious outbreak requires prompt and accurate identification of the biological agent. Often, early clinical symptoms are first identified in exposed individuals and then infectious agents are identified by lab tests. In this experiment, students transmit a simulated infectious agent (chemical dye) between classmates which is only visible under long UV light. The pattern of transmission and primary source is documented.

Infectious agents such as bacteria and viruses can spread rapidly through a population and cause widespready disease and death. In this experiment, students use coloured solutions to simulate the spreading of a disease in the classroom.

DNA mapping is a common procedure used to determine the location of genes. In this experiment, DNA markers and pre-digested plasmid DNA fragments are mapped using agarose gel electrophoresis.

Evidence left behind at a crime scene can identify a potential culprit. Even in this age of DNA, fingerprints and blood stains are still important in helping to identify a criminal. In this experiment, students solve a crime by dusting for fingerprints and use fluorescent dust to search for and identify trace amounts of blood.

With this kit, students sample water and air and then grow any microbes present overnight. A safe and simple way to teach pollution.

In this experiment, students determine a pedigree for a family thought to be carriers of a mutation in their p53 genes. This is followed by a diagnostic agarose gel analysis to diagnose the state of the p53 gene in individual family members.

DNA obtained from a single hair left behind at a crime scene can be used to identify a criminal. In this experiment, students will compare simulated crime scene DNA with that of 2 suspects.

This simple experiment demonstrates detection of the mutation that causes Sickle Cell Anaemia. In this simulation, students use electrophoresis to separate dyes that represent patient samples and controls.

This experiment helps teach students about restriction enzyme digests in the context of forensic science. Students cut DNA with restriction enzymes and then compare the banding pattern of the crime scene DNA versus that of two suspects using agarose gel electrophoresis.
