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.

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 μm, 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.

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.

Abstract: A silyl protected diacrylamide compound is described. A method of forming such a compound includes mixing a silylation reagent with a hydroxylated diamine compound under first reactive conditions to form a product in a first solution, separating the product from the first solution, and mixing the product with acryloyl chloride under second reactive conditions in a second solution to form a silyl protected diacrylamide compound.
