Many, many techniques are available to assess protein-protein interactions. One popular approach is to fuse a protein of interest to each part of a split fluorescent protein (FP) and measure the signal produced when the candidate proteins’ interaction brings the pieces of the FP ...
This post was contributed by guest blogger Daria Shcherbakova, a faculty member at Albert Einstein College of Medicine. Several sets of near-infrared fluorescent proteins (NIR FPs) and biosensors have been created recently. As developers of many of these probes, we decided to ...
We are excited to announce the recipients of this year’s Michael Davidson and Roger Tsien Commemorative Conference Awards. Congratulations to the five winners!
Have you ever wanted to measure expression of your protein of interest in a single cell? Or perhaps, you need to analyze a specific subset of cells in a complex population. Have you spent hours in the biosafety cabinet with cloning rings or following labor-intensive limiting ...
This post was contributed by Adriana Galvan, an associate professor at Emory University School of Medicine. Optogenetics and chemogenetics are powerful tools to modulate the activity of neurons and other brain cells. Since the opsins or chemogenetic receptors used in these ...
Streaking for single colonies is an integral part of any bacteriologist’s skill set. So when Dave Westenberg taught this concept in his microbiology lab course, he decided to add a bit of fun. He mixed together 10 E. coli strains producing different pigments, and tasked the ...
To respond to environmental conditions, cells must be able to detect extracellular stimuli. One way they do so is through G protein-coupled receptors (GPCRs), receptors that play many roles in signaling processes including smell, taste, sight, inflammation, and ...
This post was contributed by Patrick Miller-Rhodes from the University of Rochester Medical Center. You’ve probably heard of Forster Resonance Energy Transfer (FRET). Through the non-radiative transfer for energy between neighboring fluorophores, FRET can be used to detect the ...
