Differential scanning calorimetry (DSC) and differential scanning fluorimetry (DSF) were used to measure the transition temperatures of four proteins: RNase A, invertase, rituximab, and the NISTmAb (NIST Reference Material, RM 8671). The proteins were combined with several different fluorescent dyes...

9-(Dicyanovinyl) julolidine (DCVJ) is a fluorescent probe, which binds to a unique site on the tubulin dimer and exhibits different properties that are dependent upon its oligomeric state (Kung & Reed, 1989). DCVJ binds to tubulin, the tubulin-colchicine complex, and...

We present polarization-resolved fluorescence measurements of fluorescent molecular rotors 9-(2-carboxy-2-cyanovinyl)julolidine (CCVJ), 9-(2,2-dicyanovinyl)julolidine (DCVJ), and a meso-substituted boron dipyrromethene (BODIPY-C(12)). The photophysical properties of these molecules are highly dependent on the viscosity of the surrounding solvent. The relationship between their quantum...

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...
T Iwaki et al.
Biochemistry, 32(29), 7589-7592 (1993-07-27)
We have prepared monoclonal antibodies for the fluorescent molecular rotors 9-(2-carboxy-2-cyanovinyl)julolidine (CCVJ) and 9-(dicyanovinyl)julolidine (DCVJ). Mouse monoclonal antibody (IgG2b) prepared against CCVJ-conjugated bovine serum albumin strongly bound CCVJ and DCVJ. The CCVJ (or DCVJ) binding to IgG and Fab was...

Biochemistry, 28(16), 6678-6686 (1989-08-08)
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...

Journal of biochemistry, 109(4), 499-502 (1991-04-01)
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...

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...

To unravel the underlying principles of membrane adaptation in small systems like bacterial cells, robust approaches to characterize membrane fluidity are needed. Currently available relevant methods require advanced instrumentation and are not suitable for high-throughput settings needed to elucidate the...
