Product Image-BE-404

Experimentation kits, hydrophobic and hydrophilic proteins

Artikkenummer: (BE-404)
Produsent: G-Biosciences
Beskrivelse: 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

Artikkenummer: (BE-401)
Produsent: G-Biosciences
Beskrivelse: 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, protein fingerprinting

Artikkenummer: (BE-408)
Produsent: G-Biosciences
Beskrivelse: 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.

Product Image-BE-409

Experimentation kits, conservation of genetic information

Artikkenummer: (BE-409)
Produsent: G-Biosciences
Beskrivelse: 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 three 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.

Product Image-BE-312

Experimentation kits, expression of a recombinant protein

Artikkenummer: (BE-312)
Produsent: G-Biosciences
Beskrivelse: 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).

Product Image-BE-405

Experimentation kits, enzyme analysis

Artikkenummer: (BE-405)
Produsent: G-Biosciences
Beskrivelse: 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.

Product Image-BE-403

Experimentation kits: biodiversity study and biomass analysis

Artikkenummer: (BE-403)
Produsent: G-Biosciences
Beskrivelse: 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.

Product Image-BE-407

Experimentation kits, protein structure analysis

Artikkenummer: (BE-407)
Produsent: G-Biosciences
Beskrivelse: 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.
