Beschreibung: 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.

Beschreibung: 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.

Beschreibung: Ion exchange chromatography is used to separate charged molecules from complex biological samples. The charged molecules bind to a solid support carrying an opposite charge to the molecule. Proteins contain regions of charged groups on the surface which interact with the ion exchange groups immobilised on the solid support (resin column). Immobilized proteins are eluted by changing either pH or the salt gradient or a combination of both. This lab activity involves preparation of a crude protein extract and running ion exchange chromatography for isolation of proteins.

Beschreibung: In this lab activity, students learn to perform simple protein isolation procedures to isolate the protein fingerprint from various fresh tissues. They will compare the protein fingerprints of 4 different tissues to understand that the function of a particular organ is due to the proteins that are localised to the specific organ. Also included in this kit are four dried protein samples (from mouse liver, brain, heart and lungs) to compare as a control, if fresh tissues cannot be obtained.

Beschreibung: A hands on lab activity to study immunoaffinity chromatography and use a specific antibody to purify antigenic proteins from complex samples. This technique involves performing a chromatography procedure using antigen or antibody immobilized on a chromatographic resin. The solution containing antigen or antibody is passed through the column, which specifically and efficiently captures antibodies (antigen). The captured molecules are eluted from the column as a pure fraction. In this lab activity, students perform immunoaffinity chromatography and learn how this method is utilised in research laboratories.

Beschreibung: This lab activity is designed to study highly specific lock-key matching properties of antigen-antibody and how this highly specific interaction can be exploited as a tool for research and analysis. This study involves the use of an immunodiffusion technique in which antigen and antibody are allowed to diffuse in a solid agarose medium. When antigen and antibody meet, antigen-antibody complex is formed, which leads to precipitation. Antigen-antibody precipitate is formed in the zone where the concentration of the two matching pairs reaches an optimal known as the zone of equivalence, which results in formation of a visible opaque precipitate region in agarose medium. Those regions of precipitation can be used for determination of concentration or titer of both antigen and antibody. This Antigen-Antibody Interaction kit is a hands-on study of both Ouchterlony Double Diffusion and Radial Immunodiffusion techniques. This kit also provides additional guidance materials for teaching other types of antigen-antibody interactions concepts such as immunoelectrophoresis and immunoprecipitation.

Beschreibung: The final goal in molecular biology is often the expression of a recombinant protein. The transformed plasmids can be used as templates by the bacteria to produce protein. Students learn about essential promoters and other elements necessary for successful protein expression in bacteria, including the differences between inducible and constitutive (unregulated) expression.The Expression of a Recombinant Protein kit allows students to express a protein either constitutively or under the control of an inducible promoter, which is activated with IPTG (isopropyl-beta-D-thiogalactopyranoside).
