专利号:US-11745159-B2 优先权日:2017-10-20 标题:Heated nanowells for polynucleotide synthesis 发明人:MARSH EUGENE P; INDERMUHLE PIERRE F; PECK BILL JAMES 权利人:TWIST BIOSCIENCE CORP 摘要:Defined sequence RNA synthesis by 3′→5′ direction is now well established and currently in use for synthesis and development of vast variety of therapeutic grade RNA and Si RNA etc. A number of such synthetic RNA requires a modification or labeling of 3′-end of an oligonucleotide. The synthesis of 3′-end modified RNA requiring lipophilic, long chain ligands or chromophores, using 3′→5′ synthesis methodology is challenging, requires corresponding solid support and generally results in low coupling efficiency and lower purity of the final oligonucleotide in general because of large amount of truncated sequences containing desired hydrophobic modification. We have approached this problem by developing reverse RNA monomer phosphoramidites for RNA synthesis in 5′→3′-direction. They lead to very clean oligonucleotide synthesis allowing for introduction of various modifications at the 3′-end.
专利号:US-10465033-B2 优先权日:2016-11-10 标题:One step synthesis of ultrahigh molecular weight block copolymers 发明人:URBAN MAREK W 权利人:UNIV CLEMSON; UNIV CLEMSON RES FOUNDATION 摘要:Single-step synthesis processes for production of ultrahigh molecular weight block copolymers are described. The ultrahigh molecular weight copolymers can have a molecular weight of about 10 6 or greater and can be formed within a few hours in a surfactant-free environment. The formation process is controlled by initiator-starvation conditions in a sequential polymerization of monomers exhibiting different solubility in the solvent.
