The device includes a synthesis plate with vias, and a microfluidic patterning plate with a series ot open-faced channels that can be aligned with the vias on the synthesis plate. The device may be used to synthesize combinatorial libraries of small molecules.
专利号:US-5571677-A 优先权日:1993-07-02 标题:Convergent synthesis of branched and multiply connected macromomolecular structures 发明人:GRYAZNOV SERGEI M 权利人:LYNX THERAPEUTICS INC 摘要:The invention provides methods and compositons for convergent synthesis of branched polymers useful as molecular probes. The invention also includes several novel branched polymeric structures particularly useful for detecting target polynucleotides. Branched polymers of the invention comprise at least two branches: at least one branch is a target binding moiety capable of specifically binding to a target molecule of interest and one or more branches are signal generation moities capable of directly or indirectly generating a detectable signal. In accordance with the method of the invention branched polymers are assembled from components having phosphorothioate groups and/or haloacyl- or haloalkylamino groups. The phosphorothioate and haloacyl- or haloalkylamino groups react rapidly and efficiently when brought into contact to form thiophosphorylacyl- or thiophosphorylalkylamino bridges which.complete the assembly of a branched polymer. The method of the invention permits thorough purification and isolation of the components prior to final assembly. Incomplete branched polymers are readily separated from the desired product by standard means. The method of the invention permits the synthesis of several novel branched polymer configurations.
专利号:US-3846399-A 优先权日:1969-04-10 标题:Process for controlled stepwise synthesis of polypeptides 发明人:HIRSCHMANN R; DENKEWALTER R 权利人:MERCK & CO INC 摘要:The invention disclosed herein relates to a novel process for the controlled, stepwise synthesis of polypeptides and proteins. More particularly, it is concerned with a process for the rapid and efficient preparation of polypeptides in which multiple sequential steps are carried out without isolation of intermediate peptides. This process for the controlled stepwise synthesis of polypeptides involves reacting a starting amino acid or peptide (or derivative thereof) with an N-carboxy amino acid anhydride (or derivative thereof) in an aqueous medium under conditions of controlled pH such that the only amino group present in appreciable concentration in reactive form during the course of the reaction is the amino group in the starting amino acid or peptide.
