  • Patent number: 10221411
    Abstract: The present invention relates to a sorbent material for separation and purification of biopolymers, particularly nucleic acids, having a solid support substantially modified with a copolymer coating comprising aromatic monomers and crosslinking compounds and unsaturated esters or ethers preferably attached to the support via a vinylchlorsilane. The use of these materials for separation of nucleic acids, particularly a one-step isolation of DNA from lysates of different biological sources, is an object of the invention as well as a chromatographic column or cartridge at least partially filled with the sorbent material of the invention, a membrane-like device comprising the sorbent material of the invention, and a kit comprising the sorbent material of the invention in bulk or packed in chromatographic devices as well as other devices necessary for performing sample preparations.

  • Publication number: 20100009339
    Abstract: A method of rapid detection of influenza viruses and/or virus particles comprising a hemagglutinin and a neuraminidase component, said method comprising the steps of: a) binding the viruses and/or virus particles to a support containing at least one type of carbohydrate receptor selected from the group consisting of natural or synthetic oligosaccharide, which is conjugated to, or situated in composition with glycoproteins like glycophorin, a1-acid glycoprotein, a2-macroglobulin, ovomucoid, and combinations thereof which carbohydrate receptor binds to the hemagglutinin component of the viruses and/or virus particles; b) reacting the neuraminidase component of the bound viruses and/or virus particles with its labelled enzyme substrate, causing the generation of a detectable signal; and c) detecting the signal generated in step b).

  • Publication number: 20080015341
    Abstract: A composite material having a support which is at least partially covered by a hydrophobic polymer comprising fluorine moieties obtainable by a process comprising the steps of contacting the support with a crosslinkable compound having at least one olefinic double bond until the support at its surface is at least partially covered with the crosslinkable compound having at least one olefinic double bond, followed by fluorination of the support at least partially covered with the crosslinkable compound having at least one olefinic double bond, removal of unreacted material, if any, and recovering the composite material having a support which is at least partially covered by a hydrophobic polymer comprising fluorine moieties.

  • Publication number: 20070082354
    Abstract: A method for isolating RNA from RNA containing samples wherein the RNA containing sample is treated with at least one DNase and/or another enzyme like proteases or collagenases for purification of RNA in presence of a complex of ribonucleosides and the oxovanadyl ion which is capable of inhibiting RNases present in the RNA containing samples and removing the complex of ribonucleosides and the oxovanadyl ion prior to down-stream processing of the RNA of the RNA containing sample by contacting the sample of the forgoing step with a chelating agent immobilized to a support, the chelating agent having sufficient affinity to the complex of ribonucleosides and the oxovanadyl ion so that it binds to the chemical entity and the RNA containing sample is freed from the inhibitor.
