Christopher Dieni

Chris is an alumnus of Concordia University in Montreal, Quebec, Canada, where he completed his undergraduate degree and researched peroxisome biogenesis mutations in yeast. He has a Ph.D. in Chemistry from Carleton University in Ottawa, Ontario, Canada, where he studied the comparative biochemistry and physiology of frogs that could freeze solid and thaw back to life, as naturally as we go to sleep and wake up. Chris then moved to a postdoc at Penn State, studying the regulation of protein complexes in cancer biochemistry. He is currently back in Montreal, working in the biotech industry of probiotics. His interests lie in metabolic adaptation to stress, with a focus on enzymology, reversible protein phosphorylation and signal transduction.

Working with Enzymes: Part I -The Simple Kinetic Spectrophotometric Assay

Working with Enzymes: Part I -The Simple Kinetic Spectrophotometric Assay

By Christopher Dieni | April 18, 2011

At the end of my last article, I provided some practical tips and tricks for working with enzymes at the bench. Now, we’ll cover one of the cornerstone techniques of enzymology work: the enzyme assay. Starting with the simple assays and eventually working our way to the more complex, this article introduces the principles of…

Working with Enzymes: Stability, Purification and Activity

By Christopher Dieni | March 16, 2011

In Part 1 of this series, we began our journey into the fascinating world of enzymology. We looked at the most basic concepts of what an enzyme is and the incredible jobs it can do. In Part 2 of “Working with Enzymes,” I will look at some things that you should keep in mind to…

So You Want to Work With Enzymes: What Is An Enzyme?

By Christopher Dieni | February 7, 2011

Protein kinases and protein phosphatases phosphorylate and dephosphorylate a plethora of proteins. They are responsible for regulating the majority of cellular activities. Because of their importance, they can seem intimidating to tackle as a research project. At the end of the day however, kinases and phosphatases are- simply put- enzymes. Therefore, you can standard enzyme…

Basics of Protein Phosphorylation Part III: Family Ties – Diversity and Similarity Among Protein Kinases

By Christopher Dieni | September 29, 2010

So far in our “Basics” series, we’ve taken an overview of the major players involved in protein phosphorylation, and some of the tools that one might use to study them. Now, we’ll return to the protein kinases to take a deeper look- though our “deeper” look will barely scratch the surface, as there are currently…

Basics of Protein Phosphorylation Part II: Tools of the Trade

By Christopher Dieni | August 30, 2010

In the previous article in this series, we looked at the major players involved in protein phosphorylation: protein kinases, protein phosphatases, and target proteins. This time, we’ll glance over some of the tools that we can use to study various aspects of protein phosphorylation, focussing on a few I’ve personally come across. 1. Tools for…

Basics of Protein Phosphorylation Part I: Introducing the Candidates

By Christopher Dieni | July 1, 2010

The focus of my grad studies and postdoctoral research has been the analysis of proteins regulated by reversible protein phosphorylation. However, the number of unique facets in which protein phosphorylation can be studied is astounding, and is diverse as any niche of the biosciences. This article is the first in a series that will give…

Where Did Bio Begin For You?

By Christopher Dieni | February 5, 2010

Where did bio begin for you? That intriguing question has been the central focus of an interesting experience I just had. How this all started It began on a Saturday morning. After I woke up and fed my cat, and before making my own breakfast, I went straight to my computer to check which emails…
