In a recent publication, researchers from the University of Miami Miller School of Medicine (USA) describe that Serotonin released by human beta cell inhibits glucagon secretion by alpha cells. They demonstrated that this paracrine loop was mediated via the cAMP pathway. To do so, they captured in live human pancreatic islet cells cAMP signals using a specific fluorescent biosensor.
New HYDROP fluorescent dye for intracellular ROS measurement
Reactive oxygen species (ROS) play key roles in various intracellular processes and have been shown to be involved in many diseases (eg. carcinogenesis, inflammation…). Each of the ROS species is likely to have a specific role in living cells. Therefore, there is an emerging need for selectively detecting each species of ROS through conventional biochemical assays, but also in live cell imaging (see a previous post “Reactive Oxygen Species (ROS) and related assay kits“).
3 fluorescent probes that will count in 2017
The detection of molecular events in living cells is booming. In this post, we look at 3 fluorescent probes that will undoubtedly count in the live-cell imaging landscape in 2017.
MitoPeDPP: a new mitochondrial fluorescent probe for live cell imaging
Dojindo just completed its offer in the field of mitochondrial research with the release of a unique fluorescent dye for live cell imaging. This post introduces this new MitoPeDPP mitochondrial probe.
DyLight™ will be your routine fluorescent dye
Rockland Immunochemicals have developed a suite of fluorescent dyes (DyLight™) with unique fluorescence intensity and photostability. Here, we take a look at how DyLight™ dyes have all the characteristics and potential to become your daily fluorescent dye conjugates.
