The molecular rotor 9-(2-Carboxy-2-cyanovinyl)julolidine (CCVJ) is presumed to have a sensitivity towards velocity or shear which is supposed to result in a change in fluorescence quantum yield. Furthermore, a previously reported photoisomeric behavior may contribute to the measured fluorescence intensity

Sub-visible particles were shown to facilitate unwanted immunogenicity of protein therapeutics. To understand the root cause of this phenomenon, a comprehensive analysis of these particles is required. We aimed at establishing a flow-cytometry-based technology to analyze the amount, size distribution

9-(Dicyanovinyl)julolidine (DCVJ) is a fluorescent dye whose intramolecular rotational relaxation is solvent dependent. Since its quantum yield increases with decreasing free volume, this molecule has been very useful in monitoring synthetic polymer reactions and measuring local microviscosity changes in phospholipid

A confocal fluorescence microscope was used to study the exocytotic secretory processes of mast cells in combination with an fluorescent molecular rotor, 9-(dicyanovinyl)julolidine (DCVJ). DCVJ is known to be an unique fluorescent dye which increases its quantum yield with decreasing

A molecular rotor, 9-(dicyanovinyl)julolidine (DCVJ), is a fluorescent dye whose intramolecular rotation determines its fluorescence yield [Kung, C.E. & Reed, J.K. (1989) Biochemistry 28, 6678-6686]. DCVJ binds to bovine brain calmodulin and emits strong fluorescence. In fluorescence titration experiments, the
