摘要: The present invention relates to a separation matrix comprised of a support to the surfaces of which polymer chains have been coupled, wherein each polymer chain presents recurring proton-donating groups and at least the surface of the support is substantially hydrophilic. In the most advantageous embodiment, the support is porous cross-linked agarose, the polymers are poly(acrylic acid) and the proton-donating groups are carboxyl groups. The matrix is useful e.g. to remove PEG from pegylated and/or native compounds in a liquid. Accordingly, the invention also encompasses a method, such as a chromatographic method, wherein the separation matrix according to the invention is used, for example as a pre-treatment of a reaction mixture that comprises unreacted PEG, pegylated proteins and native proteins.

摘要: Process for, in layers of a porous matrix, exhibiting the groups A, introducing a functionality using a reagent I, introducing the functionality by a reaction with the groups A. The characterizing feature is that the matrix is contacted with a functional deficiency of reagent I and that conditions and reagent I are chosen so that the reaction between reagent I and the groups A is more rapid than diffusion of reagent I in the matrix.

摘要: In an optical measuring device for measuring physical magnitudes a sensor is actuated by the physical magnitude to be measured. An optical signal generator and processor provides light signals to the sensor and processes optical output signals transmitted from the sensor. Optical fibers conduct light to the sensor and transmit light signals therefrom to optical detectors. The sensor modulates at least a portion of the light transmitted thereto such that the modulated light output therefrom transmitted to the optic processor contains measuring components representative of the magnitude to be measured and stabilizing component signals independent of the magnitude. The optical processor separates the measuring components and the stabilizing components and generates at least one measuring signal and compensating signals for stabilizing the measuring device.
