Experimentation kits, hydrophobic and hydrophilic proteins

Artikel-Nr: (BE-404)
Lieferant: G-Biosciences
Beschreibung: This lab activity is designed to demonstrate the different classes of protein molecules and their classification based on solubility. Students learn fractionation of soluble, insoluble membrane proteins, and cytoskeleton proteins from a tissue sample. The insoluble protein fraction is further fractionated into hydrophilic and hydrophobic membrane proteins. Cell membrane structure and the role of hydrophobic membrane proteins are considered. This lab activity also provides an opportunity to understand characteristics of various classes of detergents and the role of detergents in solubilisation of hydrophobic membrane proteins.

Experimentation kits, physical properties of proteins

Artikel-Nr: (BE-401)
Lieferant: G-Biosciences
Beschreibung: The Physical Properties of Proteins kit is a lab activity that enables students to investigate the physical properties of several different proteins. Students will learn about protein solubility and how it is affected by various parameters; including temperature, pH, salt and dielectric constant. They will understand about protein precipitation due to pH, high salt and in the presence of organic solvents and about protein denaturation as a result of high temperature. In addition, the kit will demonstrate how non-protein agents, such as detergents drastically alter the physical properties of protein molecules and as a result, understand the importance of detergents in protein solubilisation. This lab activity involves analysis of three different types of pure proteins and then students alter some of those properties with a detergent and re-examine physical properties of those proteins. Students are challenged to consider how physical properties of protein molecules can be exploited for purification and characterisation of proteins and apply their findings on a test sample of complex tissue extract.

Experimentation kits, conservation of genetic information

Artikel-Nr: (BE-409)
Lieferant: G-Biosciences
Beschreibung: In this lab activity, students learn to perform carefully controlled experiments to generate protein fragments using a proteolysis enzyme and then analyse the protein fragments by electrophoresis. By analysis of protein fragmentation patterns, i.e. protein fingerprints, students learn about protein sequence, structure, and their conservation. Students resolve a set of 3 functionally identical protein samples selected from throughout the animal kingdom; including human, bovine and sheep. After generating fingerprints by electrophoresis, students examine the protein fingerprint of each sample to determine the degree of conservation.

Experimentation kits, protein fingerprinting

Artikel-Nr: (BE-408)
Lieferant: G-Biosciences
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.

Experimentation kits, expression of a recombinant protein

Artikel-Nr: (BE-312)
Lieferant: G-Biosciences
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).

Experimentation kits, enzyme analysis

Artikel-Nr: (BE-405)
Lieferant: G-Biosciences
Beschreibung: 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.

Experimentation kits, protein structure analysis

Artikel-Nr: (BE-407)
Lieferant: G-Biosciences
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.

Experimentation kits: biodiversity study and biomass analysis

Artikel-Nr: (BE-403)
Lieferant: G-Biosciences
Beschreibung: Biodiversity lab activity is designed for determination of protein contents and biomass in diverse biological samples to study how biomass is related to biodiversity in nature. Students collect and catalogue plant leaf samples from a diverse group of locally available plants. This lab activity involves determination of natural weight of each plant sample, grinding a predetermined amount of each sample, and the subsequent extraction of proteins from the samples. Students then learn to determine protein contents of each plant sample and attempt to relate the protein content with biomass. Students in this lab activity are challenged to think, analyse, and seek answers as to why protein biomasses vary for a given natural weight for different plants. Finally, they will relate that finding to the biodiversity of nature.

Experimentierkits, Blau-/Weißklonierung eines DNA-Fragments und Untersuchung der ß-Galactosidase

Artikel-Nr: (EDVO300)
Lieferant: EDVOTEK
Beschreibung: 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.
