The second assay used to confirm a positive HIV ELISA result is the Western blot. Using this kit, students separate protein samples from hypothetical patients on agarose gels. The proteins are then transferred to a membrane and simulated HIV proteins are detected.

Genetic testing can be used to identify people with a genetic condition which caused them to have an elevated level of cholesterol and which can be fatal. Students can see how genetic testing is carried out and learn about DNA electrophoresis.

This Ready-to-Load™ kit shows how a restriction enzyme can be used to screen DNA for Sickle Cell Anaemia.

Supplier: EDVOTEK

For learning about the diversity of proteins by studying the electrophoretic profiles of various sources. Students separate proteins from bacterial, plant, serum, and milk proteins alongside a standard protein marker.

Supplier: EDVOTEK

In this PCR experiment, students make billions of copies of a small amount of DNA in only 90 minutes. They just need to mix template DNA and primers with PCR beads that contain all of the other components required to carry out a PCR reaction. Students see the increasing amounts of DNA for themselves, taking samples every few cycles and analysing them on a DNA gel.

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.

InstaStain® methylene blue sheets stain gels in minutes and give high quality and uniform staining with excellent results for photography.

Supplier: EDVOTEK

In this kit, a set of multi-coloured links demonstate a variety of molecular biology simulations. Students learn about digesting DNA with restriction enzymes, cloning genes in plasmids, protein structure, and more.

Supplier: EDVOTEK

Kit allows students to construct DNA models and then extract DNA from onions, strawberries or bananas.

Supplier: EDVOTEK

Experiment using fluorescence and electrophoresis to solve the mystery of the invisible bands.

Supplier: EDVOTEK

In this experiment kit, students will explore four unique experiments that utilise agarose gel electrophoresis to separate DNA samples. The DNA banding patterns will be analysed within scenarios that examine forensic, medical, and scientific investigations.

Supplier: EDVOTEK

Urinalysis is one of the oldest medical diagnostic tests, and is still one of the most commonly used tests to this day.

Supplier: EDVOTEK

For vertical polyacrylamide gel electrophoresis.

Supplier: EDVOTEK

A set of coloured beads that can be designated to represent the Watson-Crick DNA bases: A, T, G, C.

Supplier: EDVOTEK

Plasmid and lambda DNA are pre-digested with restriction endonucleases that recognise and cut double-stranded DNA within or near defined base sequences. Digests are separated by agarose gel electrophoresis.

Supplier: EDVOTEK

This easy and safe experiment allows students to learn about enzyme catalysis, the nature of enzyme action, and protein structure-function relationship. Students will perform an enzyme assay and determine the rate of the enzymatic reaction.

Supplier: EDVOTEK

Small-scale, rapid isolation of plasmid DNA is a routine procedure used for screening and analysis of recombinant DNAs in cloning and sub-cloning experiments. In this experiment, students isolate plasmid DNA without the use of toxic chemicals such as phenol or chloroform.

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.

An HIV test detects HIV infection indirectly using an ELISA test against HIV antibodies in the blood. The test works by taking antibodies from the patient's blood and adding them to a microtitre plate coated with HIV antigen. If HIV antibodies are present, they will bind to the antigens on the plate. In this experiment, students perform an ELISA text by coating microtitre plate wells with simulated HIV antigen and then test simulated donor serum for anti-HIV antibodies.

Solve the mystery of two boys separated from their parents a decade ago. Their biological mother is identified by mitrochondrial DNA and their biological father from chromosomal DNA.

Supplier: EDVOTEK

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.

Kit for teaching students how to use a micropipette with ease and accuracy using multi-coloured dyes.

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.
