The Correct Way To Quantify Cellular Autophagy

The Correct Way To Quantify Cellular Autophagy

Just like you need to clean up your room from time to time, your cells also need to do a bit of housekeeping.  Your cells accomplish this through a process called autophagy.  Autophagy mainly serves two roles.  The first is to remove damaging materials, such as misfolded proteins, dysfunctional organelles, and foreign invaders.  The second…

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…

Quantifying Individual Proteins Per Bacterial Cell

Quantifying Individual Proteins Per Bacterial Cell

I’m a simple molecular biologist. It’s awesome how computational biologists use math to reduce and rebuild biological phenomenon. In my own way, I also like to reduce my observations to numbers. As a budding biochemist, I need to assemble and quantify the players in my pathway to truly understand it. In particular, I am interested…

Guidelines for Efficient Cell Sorting – Part 1

Flow cytometry is a pervasive tool to characterize just about anything in cell biology. From quantifying the expression of surface antigens, to determining the physiological changes in cells and everything in between, flow cytometry is as indispensable to a cell biologist as a knife is to a surgeon. Cell sorting is pivotal in enabling researchers…
