An Experimental Tool-kit for Measuring Protein Stability

An Experimental Tool-kit for Measuring Protein Stability

Proteins in the cell are in a constant flux governed by events including synthesis and degradation. In an effort to make cells more efficient by reducing the unnecessary protein load, most proteins in the cell have a specifically defined half-life. Another reason why cells have evolved to degrade proteins is to ensure timely removal of…

Brefeldin A v Monensin: How to Hunt for Proteins

As any good biologist knows, one of the easiest ways to determine if a cell is functionally active is the production and secretion of proteins in response to a stimulus. In many circumstances, the quantity of the secreted protein, and thus the level of cellular activation can be assessed by ELISA. However, if you are…

Have a BLAST With Your Protein Sequences

Have a BLAST With Your Protein Sequences

When I was being trained in microbiology as an undergrad, one of the first skills I acquired was the ability to quickly compare and visualize amino acid sequences using BLAST and ClustalW. 15 years later, those two programs have done nothing but improve by expanding the data contained in these databases and simplifying the user…
