标题:Dynamic covalent chemistry of spiropyrans for synthesis of photoswitchable photoinitiators and uses thereof
发明人：GARMSHAUSEN YVES
权利人:XOLO GMBH
摘要:The present invention relates to spiropyrans and process for the manufacture of them. In particular, a method is provided to exchange the indole and salicylaldehyde part of a spiropyran in a reversible reaction. The method is used for the synthesis of dual color photoinitiators with specific substituents and substitution patterns, which result in improved dual color volumetric printing (xolography). Furthermore, a process for locally polymerizing a starting material by dual color photopolymerization is disclosed.

标题:Method for enzymatic synthesis of oligonucleotides
发明人：HYMAN EDWARD D
摘要:Enzymatic synthesis of oligonucleotides may be performed in a single vessel without intermediate purification, by the steps of: n (a) combining a nucleotide primer sequence and a blocked nucleotide in the presence of a chain extending enzyme whereby a reaction mixture is formed containing the blocked nucleotide coupled to the nucleotide primer sequence at its 3' end; n (b) inactivating the chain extending enzyme; n (c) removing the blocking group from the primer-blocked nucleotide to form a primer-nucleotide product; and converting any unreacted blocked nucleotide to an unreactive form which is substantially less active as a substrate for the chain extending enzyme than the blocked nucleotide.

发明人：HANNA MICHELLE M
权利人:RIBOMED BIOTECHNOLOGIES INC
摘要:The present invention provides methods for detecting the presence of a target molecule by generating multiple detectable oligonucleotides through reiterative enzymatic oligonucleotide synthesis events on a defined polynucleotide sequence. The methods generally comprise using a nucleoside, a mononucleotide, an oligonucleotide, or a polynucleotide, or analog thereof, to initiate synthesis of an oligonucleotide product that is substantially complementary to a target site on the defined polynucleotide sequence; optionally using nucleotides or nucleotide analogs as oligonucleotide chain elongators; using a chain terminator to terminate the polymerization reaction; and detecting multiple oligonucleotide products that have been synthesized by the polymerase. In one aspect, the invention provides a method for detecting a target protein, DNA or RNA by generating multiple detectable RNA oligoribonucleotides by abortive transcription.

发明人：HANNA MICHELLE M
摘要:The present invention provides methods for detecting the presence of a target molecule by the use of nucleotide analogs containing moieties that enable detection. Such analogs may be incorporated into nucleic acids. In one embodiment, nucleotide analogs are used in a process generating multiple detectable oligonucleotides through reiterative enzymatic oligonucleotide synthesis events on a defined polynucleotide sequence. The methods generally comprise using a nucleoside, a mononucleotide, an oligonucleotide, or a polynucleotide, or analog thereof, to initiate synthesis of an oligonucleotide product that is substantially complementary to a target site on the defined polynucleotide sequence; optionally using nucleotides or nucleotide analogs as oligonucleotide chain elongators or chain terminators to terminate the polymerization reaction; and detecting multiple oligonucleotide products that have been synthesized by the polymerase.

摘要:A method of producing a monomer of a Shiga toxin B-subunit (STxB) protein or of a variant thereof by peptide chemical synthesis, as well as to a method of producing a pentamer of the STxB protein or of the variant thereof. The methods are particularly advantageous as they overcome major issues typically observed in peptide chemical synthesis, including solubility and purity issues.
