Our Bioscience Excellence Protein & Proteomic Kits are designed to teach students the fundamentals of protein structure and function as well as commonly used laboratory techniques including protein quantification, protein electrophoresis, and protein purification.

The cellular environment is a constant dynamic with the continued synthesis, degradation and recycling of protein molecules.  This dynamic allows for close regulation of cellular processes by switching off cellular pathways by degrading key proteins. The degradation of proteins is controlled an..

An important and essential tool in protein analysis is electrophoresis.  Protein electrophoresis allows researchers to separate complex protein samples by their molecular size and/or net charge on polyacrylamide gels.  The proteins can be subsequently visualized with various protein stains..

Each tissue of an organism performs a specific function, for example, the heart has a completely different role than that of the brain.  The diverse functions of an organism’s tissues is due to the protein make-up, or fingerprint, of the tissue.  Each organ contains specialized prote..

A proteins life cycle begins once its gene is turned on and its mRNA is transcribed and translated to produce the polypeptide strand. The correct folding of a protein is the first crucial stage of the life cycle of a protein. Correct folding is essential for a protein to be functional, whereas incor..

The aim of proteomics is to identify and characterize all the proteins in an organism.  The major restrictions in protein identification are the large number of proteins and the huge differences in abundance.  These restrictions mean low abundance, critical proteins are often masked and ar..

Proteomics often involves the purification and identification of novel proteins from tissues.  The strategy often employed is one using multiple and different protein purification techniques to fractionate proteins into specific fractions.  This allows for easier identification and charact..

This lab activity has two objectives, on one hand it is designed to deepen the understanding of protein molecules. On the other hand, students also learn the potential of electrophoresis in protein analysis.   Students study the fundamentals of protein structure from their primary structure ..

Molecular cloning is a commonly used technique for the generation of recombinant proteins.  The gene for a protein of interest is cloned into a vector, or plasmid, in frame with the gene for a protein tag.  These tags are used to purify expressed protein by established methodologies. ..

Size exclusion chromatography (SEC), also called gel filtration chromatography or gel-permeation chromatography (GPC), uses porous particles to separate molecules of different sizes.  It is generally used to separate biological molecules and to determine molecular weights and molecular weight d..

Proteins within a cell are often localized to specific cellular compartments, such as the nucleus, mitochondria, plasma membrane, or vesicles and their specific localization can provide crucial information about the function of the protein.  An important technique in identifying novel proteins ..

Zymography is an electrophoretic technique that includes a substrate copolymerised with the polyacrylamide gel for the detection of enzymes and their activity. Samples are prepared without denaturing the active enzymes present in the samples. Following electrophoresis, the gel is placed in an enzyme..

This kit is designed to teach 8 groups of four students the principles of Ion Exchange Chromatography and protein purification.  The kit contains the reagents to allow students to: Equilibrate a DEAE agarose column Load a protein sample on the column (amylase, lysozyme or a mixture of both)..
