  • Patent number: 11261480
    Abstract: A method for processing a nucleic acid, in which the nucleic acid is exposed to an aqueous medium which includes a polyol in sufficient proportion for at least a portion of the nucleic acid to enter or remain in an extra-solution phase. Thus, a polyol may be used to bind a nucleic acid which is in solution to a solid support or to wash a nucleic acid on a solid support whilst maintaining it on the support. The polyol may for example be a C2-C10 alkanediol.
    Type: Grant

  • Publication number: 20190233558
    Abstract: A method of forming a particle includes, in a disperse phase within an aqueous suspension, polymerizing a plurality of mer units of a hydrophilic monomer having a hydrophobic protection group, thereby forming a polymeric particle including a plurality of the hydrophobic protection groups. The method further includes converting the polymeric particle to a hydrophilic particle.

  • Patent number: 10017586
    Abstract: This invention relates to monodisperse cross-linked polymer particles, comprising particles with a substantially smooth outer surface and an average diameter of less than 1 ?m, wherein the particles are solid or porous, and wherein the coefficient of variation (CV) % of the particles, when measured by CPS disk centrifugation analysis, is less than 15%. These monodisperse cross-linked polymer particles may comprise magnetic material and are useful in various application. This invention also relates to monodisperse polymer particles for use as seed particles in the Ugelstad process.
