Imagem do Produto-BE-301

Experimentation kits, bacterial conjugation

Código de Artigo: (BE-301)
Fornecedor: G-Biosciences
Descrição: Bacterial conjugation is a naturally occurring process that allows the transfer of DNA from one bacterium to another, which allows the transfer of genetic traits, particularly drug resistance. The kit contains two bacteria with different drug resistance genes and all the tools for students to study bacterial conjugation. This kit teaches the difference between bacterial genomic DNA and the transferable plasmid DNA and the mechanisms of bacterial conjugation. Students will also learn important basic microbiological techniques, including bacterial growth in liquid broth and on solid agar plates, antibiotic selection of bacteria and important aseptic techniques.

Experimentation kits, Mini-Prep isolation of plasmid DNA

Código de Artigo: (EDVO202)
Fornecedor: EDVOTEK
Descrição: Small-scale, rapid isolation of plasmid DNA is a routine procedure used for screening and analysis of recombinant DNAs in cloning and sub-cloning experiments. In this experiment, students isolate plasmid DNA without the use of toxic chemicals such as phenol or chloroform.

Experimentation kits, cleavage of Lambda DNA with Eco RI endonuclease: intro to restriction enzymes

Código de Artigo: (EDVO212)
Fornecedor: EDVOTEK
Descrição: 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.

Experimentation kits, assays for protein quantification

Fornecedor: G-Biosciences
Descrição: 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.

Experimentation kits, enzyme analysis

Código de Artigo: (BE-405)
Fornecedor: G-Biosciences
Descrição: 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, DNA ligation

Código de Artigo: (BE-308)
Fornecedor: G-Biosciences
Descrição: 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.

Experimentation kits, survey of protein diversity (polyacrylamide-based)

Código de Artigo: (EDVO150)
Fornecedor: EDVOTEK
Descrição: For learning about the diversity of proteins by studying the electrophoretic profiles of various sources. Students separate proteins from bacterial, plant, serum, and milk proteins alongside a standard protein marker.

Experimentation kits, conservation of genetic information

Código de Artigo: (BE-409)
Fornecedor: G-Biosciences
Descrição: 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.

Imagem do Produto-BE-414

Experimentation kits, size exclusion chromatography

Código de Artigo: (BE-414)
Fornecedor: G-Biosciences
Descrição: The Size Exclusion Chromatography kit teaches gel filtration or size exclusion chromatography and the use of this method in purification of biological samples. This method is based on separation of protein molecules based on their molecular size. This lab activity involves running size exclusion chromatography for separation of molecules based on their molecular sizes.

Ready-to-Load™ kits, cholesterol diagnostics

Fornecedor: EDVOTEK
Descrição: Genetic testing can be used to identify people with a genetic condition which caused them to have an elevated level of cholesterol and which can be fatal. Students can see how genetic testing is carried out and learn about DNA electrophoresis.

Transformation of E. coli with pGAL™

Código de Artigo: (EDVO221)
Fornecedor: EDVOTEK
Descrição: 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.

Experimentation kits, protein fingerprinting

Código de Artigo: (BE-408)
Fornecedor: G-Biosciences
Descrição: 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.
