  • 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.
