Taq DNA polymerase
Supplier: G-Biosciences
Taq DNA Polymerase is a highly thermostable recombinant DNA polymerase derived from the thermophile Thermus aquaticus. The molecular weight of the recombinant protein is 94 kD. The Taq Polymerase is able to amplify DNA up to 5 kb with an elongation velocity of 0,9 to 1,2 kb/min at 70 to 75 °C. The error rate of this Taq Polymerase is ~2,2×10⁻⁵ nucleotide⁻¹ cycle⁻¹. Taq DNA polymerase catalyses the 5’→3’ synthesis of DNA. The enzyme has no detectable 3’→5’ proofreading exonuclease activity, and possesses low 5’→3’ exonuclease activity, which results in a 3’-dA overhang on the PCR product

Agarose IV, powder, Highest Gel Strength for biotechnology
Supplier: G-Biosciences
G-Biosciences offers several different biotechnology-grade agarose powders. Agarose IV is a linear polymer with a very high molecular weight, giving gel structures unlike those of traditional agaroses. This characteristic produces a strong intercatenary interaction, yeilding a gel with very high gel strength and higher exclusion limit.

IgG purification kits, Pearl™
Supplier: G-Biosciences
The Pearl™ IgG purification kits are designed for the one step purification of IgG antibodies from serum. The supplied Pearl™ IgG purification resin binds the high abundant, non-IgG proteins (i.e. albumin) and allows the IgG molecules to pass through in a physiological buffer. The purified IgG molecules can be stored or used in further downstream applications without further clean-up, such as ammonium sulphate precipitation.

Experimentation kits, dialysis
Supplier: G-Biosciences
Dialysis is a routinely used technique in research laboratories to 'change' the solution a biomolecule is dissolved in. Often the buffers used to isolate biomolecules, such as proteins, are not compatible with downstream applications due to high concentrations of reagents, such as salts. A sample is placed in a bag with a semi-permeable membrane and then placed in the new solution or water. Small molecules, such as salt, can pass through the membrane, moving from an area of high concentration to low concentration. The larger molecules, such as proteins, are retained in the bag. Microdialysis is a modification of dialysis to overcome the problem of dialysing small volumes of precious samples. Microdialysis uses small devices designed for small volumes. This kit allows students to study dialysis using patented microdialysis devices.

Experimentation kits, protein electrophoresis
Supplier: G-Biosciences
Using the Protein Electrophoresis kit, students will learn the principles of various types of electrophoresis, including denaturing and non-denaturing electrophoresis, and how this powerful technique is used to analyse proteins. The kit will introduce students to the different separation matrices currently in use and will understand their differing separation properties and their role in protein analysis. Students have an option of casting their own electrophoresis gels using polyacrylamide or using pre-cast commercially available gels. This kit is provided with all of the reagents, buffers and supplies needed for casting acrylamide gels, preparing protein samples, running electrophoresis, and staining the gels for visualisation of protein bands. Test protein samples and protein standards are also provided.

Experimentation kits, conservation of genetic information
Supplier: G-Biosciences
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.
