  • Publication number: 20170002152
    Abstract: A polymer substrate, such as a polymer particle, is formed from a carboxyl functional monomer. In an example, the carboxyl functional monomer has a protection group in place of the OH of the carboxyl group. Once the monomer is polymerized, such a protection group can be removed, providing a polymer network with carboxyl functional sites. Such sites can be used to attach other functionality to the polymer substrate.

  • Publication number: 20170002410
    Abstract: A polymer substrate, such as a polymer coating or a polymer hydrogel network, includes carboxyl moieties that can be used as conjugation sites to which receptor or analyte molecules can be attached. In an example, the polymer substrate includes a polyacrylamide polymer network having alkanoic acid moieties or derivatives thereof, which can react with carboxyl activating compounds to provide an activated alkanoate moieties on the polyacrylamide network Amine-terminated nucleic acids can react with the activated alkanoate moieties to capture the nucleic acid to the polymer network through an alkylamide moiety.

  • Publication number: 20160326291
    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.

  • Publication number: 20160186166
    Abstract: The disclosure generally relates to compositions and methods for the production of nucleic acid molecules. In some aspects, the invention allows for the microscale generation of nucleic acid molecules, optionally followed by assembly of these nucleic acid molecules into larger molecules. In some aspects, the invention allows for efficient production of nucleic acid molecules (e.g., large nucleic acid molecules such as genomes).

  • Publication number: 20160115524
    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.

  • Patent number: 9309368
    Abstract: A process for the preparation of monodisperse polymer particles which are formed by contacting monomers with aqueous dispersions comprising monodisperse swellable seed polymers/oligomers, and initiating polymerization in the presence of a steric stabilizer. The resulting swollen seed particles are characterized by the particle mode diameter.
