摘要:
This invention provides methods for removing unincorporated dye-labeled molecules from a mixture that includes dye-labeled polynucleotides or other polymers and the unincorporated dye-labeled molecules. The methods involve adsorbing the unincorporated dye-labeled molecules into a plurality of particles that are made up of one or more porous hydrophobic materials that are encapsulated in a hydrophilic matrix.
摘要:
The present invention provides arylboronic acid reagents useful for incorporation into modified oligonucleotides and polynucleotides. The modified oligonucleotides and polynucleotides thus produced are useful in bioconjugation reactions for the immobilization and purification of macromolecules.
摘要:
Modified nucleotides and polynucleotides which are useful in hybridization assays for the detection of target genes are provided. The modified polynucleotides contain at least one boronic acid moiety which is attached to a nucleotide base in a position which does not interfere with the hydrogen bonding capabilities of that base during duplex formation. The modified polynucleotides are typically formed from naturally occurring nucleotides and one or more modified nucleotides.

This invention provides methods for removing unincorporated fluorescent dye-labeled molecules from a mixture that includes fluorescently-labeled polynucleotides and the unincorporated fluorescent dye-labeled molecules. The methods involve adsorbing the unincorporated fluorescent dye-labeled molecules into a plurality of particles that are made up of one or more porous hydrophobic materials that are encapsulated in a hydrophilic matrix.
摘要:
The present invention relates to the field of nucleic acid immobilization, purification and detection and, more particularly, to boronic acid modified oligonucleotides and polynucleotides useful in bioconjugation reactions. The modified oligonucleotides and polynucleotides are useful in reactions for the immobilization and purification of macromolecules.

摘要:
Provided herein are duplex oligonucleotide complexes which can be administered to a cell, tissue or organism to silence a target gene without the aid of a transfection reagent(s). The duplex oligonucleotide complexes of the disclosure include a conjugate moiety that facilitates delivery to a cell, tissue or organism.
摘要:
Methods and compositions for making nucleoside phosphoramidites and nucleic acids, including mono-, di-, and polynucleotides, comprising a linker covalently attached to a levulinyl moiety are provided. A levulinyl-protected linking moiety affords an orthogonal approach to modifying a polynucleotide during or after solid phase synthesis with a molecule of interest, for example, a conjugate or a dye.
