    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.

    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: The present invention relates to a method of isolating at least one plasmid from other components of a liquid, which method comprises the steps of providing a separation matrix comprised of one or more porous carriers, which carrier(s) present anion exchange groups on external surfaces as well as pore surfaces and a pore size distribution that does not allow access of plasmids to pore surfaces; contacting said matrix with the liquid to allow adsorption of the plasmids to ligands present on the separation matrix; contacting an eluent with the separation matrix to release the plasmids and recovering plasmids from a fraction of said eluent. Thus, the present method allows the plasmids to adsorb to the external surfaces of the matrix, while other components such as RNA is adsorbed onto the pore surfaces. In one embodiment, the matrix presents a DNA exclusion limit of at least about 270 base pairs; such as at least about 1,000 base pairs.
