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.

摘要:Methods for the automated template-free synthesis of user-defined sequence controlled biopolymers using microfluidic devices are described. The methods facilitate simultaneous synthesis of up to thousands of uniquely addressed biopolymers from the controlled movement and combination of regents as fluid droplets using microfluidic and EWOD-based systems. In some forms, biopolymers including nucleic acids, peptides, carbohydrates, and lipids are synthesized from step-wise assembly of building blocks based on a user-defined sequence of droplet movements. In some forms, the methods synthesize uniquely addressed nucleic acids of up to 1,000 nucleotides in length. Methods for adding, removing and changing barcodes on biopolymers are also provided. Biopolymers synthesized according to the methods, and libraries and databases thereof are also described. Modified biopolymers, including chemically modified nucleotides and biopolymers conjugated to other molecules are described.

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:The present invention provides modified cycloalkyne compounds; and method of use of such compounds in modifying biomolecules. The present invention features a cycloaddition reaction that can be carried out under physiological conditions. In general, the invention involves reacting a modified cycloalkyne with an azide moiety on a target biomolecule, generating a covalently modified biomolecule. The selectivity of the reaction and its compatibility with aqueous environments provide for its application in vivo (e.g., on the cell surface or intracellularly) and in vitro (e.g., synthesis of peptides and other polymers, production of modified (e.g., labeled) amino acids).

摘要:The present invention relates to a multifunctional molecule which is capable of initiating first and/or second strand DNA synthesis of a retroviral RNA genome or derivatives thereof. The multifunctional molecule comprises a first part complementary to a part of the retroviral RNA genome or derivatives thereof. A second part of the multifunctional molecule comprises genetic elements and/or labels. The genetic elements may be gene cassettes for the expression of proteins, peptides or polypeptides or for example functional RNA elements such as shRNA, siRNA, miRNA and the like. The multifunctional molecule represents a novel tool for insertion of genes into host cell genomes. The present invention therefore relates to the field of gene delivery and methods employed therefore.
