In a recent Nature Communications article, researchers introduced destabilized near-infrared (NIR) fluorescent nanobodies designed to target green fluorescent protein (GFP)-based biosensors. These ...

Modern bioassays tend to fall under three common modalities: colorimetric, luminometric or fluorometric. Colorimetric assays record the amount of light absorbed by a reporter compound. This absorbance ...

A fluorescent microscope image shows that in a population of genetically identical. The cell in green is expressing a green-fluorescent protein that is expressed by cells that are able to take up DNA ...
