The aim was to evaluate fluorescent molecular rotors (DCVJ and CCVJ), which are mainly sensitive to viscosity, for the characterization of polysorbate-containing IgG formulations and compare them to the polarity-sensitive dyes ANS, Bis-ANS and Nile Red. IgG formulations with polysorbate

Fluid shear stress (FSS) has been shown to be an ubiquitous stimulator of mammalian cell metabolism. Although many of the intracellular signal transduction pathways have been characterized, the primary mechanoreceptor for FSS remains unknown. One hypothesis is that the cytoplasmic

Di(cyano vinyl)julolidine (DCVJ) is a fluorescent probe which has been used to monitor the local mobility of its binding sites on proteins. It shows a concentration dependence of its emission spectrum in water. At higher DCVJ concentrations, a longer wavelength

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

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
