Addgenie Mary Gearing contributed to the content of this article. Biosensors (‘biological sensors’) are biological tools that monitor a process or detect a given molecule. The sensor component is usually a protein that undergoes a conformational change in response to the ...
Even before fluorescent proteins (FPs) came into wide use, there were a variety of ways to monitor cell, organelle, and protein localization. For instance, you might dye your cells and look at them under a microscope, fractionate samples to isolate particular organelles and ...
Fluorescent proteins (FPs) offer scientists a simple yet powerful way to tag cellular proteins and investigate protein localization, interaction, and expression. However, one caveat of FP-protein fusions (FP-chimeras) is that they undergo normal protein turnover. FP-chimeras are ...
What is an aptamer? Nearly 30 years ago, two independent groups, led by Jack Szostak and Larry Gold, developed methods for selecting and amplifying RNA sequences that could bind very specifically to target molecules. Using a technique called systematic evolution of ligands by ...
This post was contributed by guest blogger Erik L. Snapp. Stop using EGFP/GFP for fusion proteins! Despite multiple studies in high profile journal articles, many researchers remain unaware that EGFP/GFP is prone to forming noncovalent dimers. This property of EGFP can lead to ...
Luciferases are a class of enzymes capable of catalyzing chemical reactions in living organisms resulting in the emission of photons. The most familiar bioluminescent organism for most people is the firefly (Photinus pyralis) and perhaps not surprisingly it is also the most ...
This post was contributed by Gal Haimovich of greenfluorescentblog. Be honest. Do you really know how fluorescent proteins glow? Fluorescent Proteins (FPs) were first discovered over 50 years ago, with the discovery of the Green Fluorescent Protein (GFP), a protein from the ...
