摘要: The present invention relates to a dianhydride analysis method, which can reliably analyze a dianhydride having high reactivity and low solubility. In addition, the present invention can analyze the structure of impurities by separating the impurities on the basis of having a similar retention time in HPLC analysis, and can analyze the purity of the dianhydride with or without chromophores.

摘要: Methods for identifying viral protein constituents and quantifying the relative abundance of such viral protein constituents in a sample of viral particles are disclosed. In embodiments, the methods include first-dimension chromatography to separate intact viral capsid components of the sample, online denaturation of the viral capsid components to produce intact viral proteins, second-dimension chromatography to separate the viral proteins, and mass spectrometry to determine the masses of the viral proteins and identify the viral protein constituents of the sample.

摘要: When an operation receiver receives an operation for starting automatic start-up processing, a display controller causes a display to display a first direction image indicating a working order of a plurality of objects to be controlled, sequentially changes a display mode of a status image corresponding to an object that has worked to a first mode, and changes a display state of each of a plurality of operation images to an operable first state or an inoperable second state. When the operation receiver receives an operation for starting automatic stop processing, the display controller causes the display to display a second direction image indicating a stopping order of the plurality of objects in a reversed manner of the first direction image, sequentially changes a display mode of a status image corresponding to an object that has stopped to a second mode.

摘要: A method of detecting particles, e. g. proteins, after separation of particles based on their specific features, e.g. charge, size, shape, density, as series of single light scattering events created by the individual particles is described. The particles are separated from each other along the separation path and particles have specific arrival times at the target side depending on the particle features. The detecting step comprises an interferometric sensing of the light scattered at individual particles bound or transient in the detection volume. Parameters of the scattering light signals e.g. the interferometric contrast are analyzed for obtaining specific particle features, e.g. size, mass, shape, charge, or affinity of the particles. Furthermore, a detection apparatus being configured for detecting particles is described.

摘要: The present disclosure relates to methods of modifying complex extracts such that components or mixtures of components are selectively removed or added, thus providing a complex mixture that does not naturally occur with a refined or a tuned therapeutic or nutraceutical effect. In various aspects, the complex extract can be an extract obtained from one or more plants, e.g., an extract obtained from green tea leaves. The present disclosure pertains to compositions obtained by the disclosed methods, nutraceutical compositions comprising same, pharmaceutical compositions comprising same, and methods of treating various conditions, including physiological dysfunctions associated with elevated reactive oxygen species and/or inflammatory molecule, e.g., TNFα, expression using same. This abstract is intended as a scanning tool for purposes of searching in the particular art and is not intended to be limiting of the present disclosure.
