inTroDuCTion In the preformulation stage of pharmaceuticals, accelerated stability studies using data from DSC/DTA studies, combined with analytical techniques such as spectroscopy and HPLC are the normal methods used to collect data. The possibility to use isothermal heat conduction microcalorimetry to obtain rate constants at close to, or at room temperatures could therefore be of interest fo...

Detailed stopped-flow studies in combination with site-directed mutagenesis, isothermal titration calorimetry data and x-ray crystallographic knowledge have revealed that the biphasic pre-equilibrium fluorescence changes reported for a single Ig-binding domain of protein L from Peptostreptococcus magnus binding to kappa light chain are due to the binding of the kappa light chain at two separate...

The majority of alkynyl(aryl)iodonium salts reported in the literature are derived from iodobenzene. This article describes the effects of varying this iodoarene building block on the synthesis, reactivity and stability of these salts. Two procedures to synthesize a variety of known and novel alkynyl(aryl)iodonium tosylates directly from the iodoarene are reported. In the reactions of these sal...

To apply enzymes in technical processes, a detailed understanding of the molecular mechanisms is required. Kinetic and thermodynamic parameters enzyme catalysis are crucial to plan, model, implement biocatalytic processes more efficiently. While kinetic parameters, Km kcat, often accessible by optical methods, determination requires sophisticated methods. Isothermal titration calorimetry (ITC) ...

The effect of dextran sulfate on protein aggregation was investigated to provide the clues of its biochemical mechanism. The interaction between dextran sulfate and BSA varied with the pH values of the solution, which led to the different extent of aggregation prevention by dextran sulfate. Light scattering data with thermal scan showed that dextran sulfate suppressed BSA aggregation at pH 5.1 ...
