The kit utilises the principle of diffusion of nucleic acids on a nylon membrane to determine their concentration. No spectrophotometers required.

Supplier: EDVOTEK

This Lab activity shows students what real chromosomal DNA Looks Like and allows them to explore the procedures involved in DNA extraction.

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.

Supplier: EDVOTEK

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 two suspects.

Supplier: EDVOTEK

This simulation experiment demonstrates the process of DNA amplification by PCR and how the amplified product is detected by separating the reaction mixture by agarose gel electrophoresis.

Supplier: EDVOTEK

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.

Supplier: EDVOTEK

Students can solve a crime using PCR. Plasmid DNA is provided that, when amplified by PCR, provides products that represent individual DNA profiles.

Supplier: EDVOTEK

Students learn the basic principles of the Enzyme-linked Immunosorbent Assay (ELISA) using this precise and sensitive antibody-based detection kit.

Supplier: EDVOTEK

This experiment introduces chromatographic theory and methods of thin layer chromatography (TLC). A mixture of dyes are separated on a cellulose-based TLC plate using different solvent systems.

Supplier: EDVOTEK

Kit for teaching students how to extract and precipitate their own DNA. Students can transfer their DNA to a tube that can be used as a pendant on a necklace.

Supplier: G-Biosciences

This lab activity involves analysis of an enzyme reaction using a specific enzyme substrate and inhibitor. Students study how the rate of enzyme reaction is dependent on substrate concentration and the influence of agents (inhibitors) and conditions that affects the enzyme reaction such as pH and temperature.

Supplier: EDVOTEK

This experiment introduces chromatographic separation to the class and shows students how dyes of different colours separate on the basis of their size and shape. Columns may be rinsed and reused.

Supplier: EDVOTEK

Ready-to-Load™ kit for teaching DNA fingerprinting and to show how DNA evidence is used in modern forensics. This experiment allows for varied results depending on the selection of DNA fingerprinting patterns.

Supplier: EDVOTEK

Met deze Ready-to-Load™-kit kan worden gedemonstreerd hoe een restrictie-enzym kan worden gebruikt om DNA te screenen op sikkelcelanemie.

Supplier: G-Biosciences

The Affinity Chromatography kit teaches the basic principle of affinity chromatography utilising highly specific affinity columns. This lab activity involves preparation of a crude protein extract and running affinity exchange chromatography for isolation of a protein.

Supplier: EDVOTEK

Infectious mononucleosis is commonly known as the 'kissing disease'. The causative agent is Epstein-Barr virus (EBV), which can be transmitted through saliva during kissing. In this experiment, students search for the presence of EBV using the ELISA reaction to detect specific viral proteins.

Supplier: EDVOTEK

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.

Supplier: EDVOTEK

In this experiment, students see a blue colour change in transformed cells due to the switching on of a gene. The pGAL plasmid gives a blue colour dye due to the production of the β-galactosidase protein by the lacZ gene. IPTG is not required in this experiment since pGAL contains the complete lacZ gene.

Supplier: EDVOTEK

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.

Supplier: EDVOTEK

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.

Supplier: EDVOTEK

In DNA fingerprinting, variable number tandem repeats (VNTR) are used to identify individuals. Using this kit, students type themselves at the D1S80 locus on chromosome 1. This region contains between 14 and 40 copies of a 16 base pair repeat.

Supplier: EDVOTEK

This experiment introduces students to the principles of antigen-antibody interactions by using the Ouchterlony procedure. Antibodies and antigens form complexes that precipitate, making it possible to assay antibody-antigen systems. The binding interaction results in the formation of a white precipitate after diffusion in agarose.

The DNA from bacteriophage Lambda is a well-characterised linear molecule containing six recognition sites for Eco RI (5 distinct sites, 2 are very close in size). In this experiment, Lambda DNA is digested by the Eco RI endonuclease. The digestion products are analysed by agarose gel electrophoresis.

Supplier: G-Biosciences

Following restriction enzyme digestion of DNA molecules, researchers need to rejoin the ends of the DNA to generate recombinant DNA, a process known as ligation. Ligation of DNA is achieved with the bacterial enzyme T4 DNA ligase, which catalyses the formation of phosphodiester bonds. The DNA Ligation kit teaches students about ligation as they ligate several DNA fragments together to make larger pieces of DNA that are easily identified by agarose electrophoresis.

Suppressor genes, such as p53, are essential for cell functions. Mutations in the p53 gene can be correlated to predisposition for certain cancers. Mutations of genes can either be inherited or accumulated due to environmental insults. This experiment deals with a family pedigree determination of several generations relating to cancer formation due to p53 gene mutation.
