Description: This lab activity has two objectives - to deepen the understanding of protein molecules and for students to learn the potential of electrophoresis in protein analysis. Students study the fundamentals of protein structure from their primary structure to the more complex tertiary and quaternary structures, utilising protein electrophoresis. Complex mixtures of protein samples and characterised pure protein samples, in conjunction with electrophoresis, are utilised to study protein structure and the potential of protein electrophoresis. Using non-denaturing and denaturing electrophoresis, students understand the difference between primary, tertiary and quaternary structures, the importance of disulfhydryl bridges in maintaining protein structure and electrophoresis in studying complete proteins and protein subunits.

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: Over 30% of the world's population uses tobacco products, and 90% of that is from cigarettes. The physical effects of nicotine and the diseases it can cause, including cancer, are detailed on this anatomical poster. For such a wide spread practice education is important and this anatomy poster can help do that. This thickly laminated anatomical chart is printed on premium glossy (200 g) UV resistant paper and comes with two sided lamination (125 µm, 5,0 mil) and metal eyelets to make the chart easy to display.

Catalog Number: (BE-203)

Supplier: G-Biosciences

Description: Antibiotics play a crucial role in the manipulation, screening and killing of bacteria in a range of biotechnology processes. This kit specifically teaches the basic principles of antibiotics, bacterial resistance and susceptibility. Students learn and understand the use of antibiotic resistance in screening for infectious diseases. Utilising a bacterial strain, students learn the effects of different antibiotics and visualise bacterial sensitivity and resistance to the supplied antibiotics. This method involves the use of filter paper discs impregnated with a specified concentration of antibiotics on the surface of an agar plate containing microbial cells. This kit will enable students to analyse the inhibitory effects of different antibiotics on selected bacterial cells and then determine which antibiotic is the most suitable to treat a bacterial infection.

Description: 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 <i>lacZ</i> gene. IPTG is not required in this experiment since pGAL contains the complete <i>lacZ</i> gene.

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: Determination of protein concentration is an essential technique in all aspects of protein studies and proteomics. The Assays for Protein Quantification kit includes three of the most widely used protein assays and allows for a direct comparison of the three assays that teaches students the benefits and limitations of each assay. Each assay is available individually to allow teaching of a specific assay, without the option of comparing and contrasting with other assays. The three assays covered are the Biuret Protein Assay, Lowry Protein Assay and the Coomassie Blue Dye Protein Assay. The Assays for Protein Quantification kit provides all the reagents required to perform both protein assays, including protein standards for accurate quantification, in a single lab activity. An often underestimated factor in quantifying protein is the presence of non-protein interfering agents, such as salts and detergents. This kit teaches students about common laboratory agents that affect the protein assays, the reasoning behind their interferences and how to overcome the interference. Students also learn how to select a protein assay for different applications.

Supplier: G-Biosciences

Description: This kit teaches aseptic handling techniques and cultivation of bacteria in liquid culture media and on solid phase agar plates. This kit is designed to educate students about the various stages of the bacterial growth cycle, i.e. lag, log or exponential, stationary and decline or death phases. The kit also teaches the importance of growing bacteria on solid phase agar plates to isolate single colonies of bacteria. This lab activity involves preparation of culture medium and solid agar plates.
