Rice University scientists have effectively quenched a debate over the mechanism behind a fluorescent biosensor that monitors neurons by sensing changes in voltage.The work led by Rice theoretical che...
Anomalous Negative Fluorescence Anisotropy in Yellow Fluorescent Protein (YFP 10C):Quantitative Analysis of FRET in YFP Dimers
Alzheimer's disease Amyloid beta 40 peptide Human serum albumin Circular dichroism Dissociation constant alpha-Helix
2016/5/25
Yellow fluorescent protein (YFP) is widely used as a genetically encoded fluorescent marker in biology. In the course of a comprehensive study of this protein, we observed an unusual, negative fluores...
