Supplier: EDVOTEK

Description: 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.

Description: 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.

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

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

Catalog Number: (EDVO300)

Supplier: EDVOTEK

Description: 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 <i>E. coli</i> 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.

Description: 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.

Description: Drinking water is routinely tested for contamination. If a screening tests positive, more sophisticated tests are required. One such test uses PCR in multiplex format. In this experiment, students test for the presence of three separate, classroom-safe organisms in a water sample using a single PCR reaction.

Description: 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.
