Description: <i>Taq</i> DNA Polymerase is a highly thermostable recombinant DNA polymerase derived from the thermophile <i>Thermus aquaticus</i>. The molecular weight of the recombinant protein is 94 kD. The <i>Taq</i> 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 <i>Taq</i> Polymerase is ~2,2×10⁻⁵ nucleotide⁻¹ cycle⁻¹. <i>Taq</i> 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

Description: 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.

Description: Blocking buffer is an enhanced blocking agent available in multiple formats. Superior™ Blocking Buffer contains a proprietary antigenically non-determinant protein for blocking Western blot membranes, blocking and storage of ELISA plates, and blocking prior to immunohistochemistry staining.

Description: The concentrator is a high molecular weight polymer which will not migrate across the dialysis membrane. The concentrator is placed against the dialysis membrane of the Tube-O-DIALYZER™, where it rapidly absorbs water from the sample and reduces the sample volume. The concentrator can be used with dialysis bags and other dialysis devices.

Description: The Hydrophobic Chromatography kit is designed to teach students the basic principle of hydrophobic chromatography utilising a hydrophobic enzyme. The use of the enzyme allows purification followed by a simple enzyme assay to detect the fractions that contain the enzyme. This lab activity involves preparation of a crude protein extract and running hydrophobic chromatography to isolate the enzyme.

Description: 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.

Description: 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.

Catalog Number: (BE-409)

Supplier: G-Biosciences

Description: 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.
