A single protein molecule rarely carries out its role in the body on its own. Many proteins and cofactors are often involved and act as regulators, activators or inhibitors of the...

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...

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...

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...

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...

huge differences in abundance.  These restrictions mean low abundance, critical proteins are often masked and are therefore hard to identify and purify.  One key tool in resolving this issue is...
