摘要: The invention provides compositions and methods for assembling a DNA molecule having a desired sequence. The methods involve contacting a DNA polymerase, dNTPs, and a plurality of pairs of oligonucleotides. The oligonucleotides of a pair have a portion of the desired sequence, and an internal sequence that overlaps and is complementary to an internal sequence of the other oligonucleotide of the pair, and, when arranged in order, they have at least a portion of the desired sequence. The oligonucleotides also have a 3′ or a 5′ primer binding sequence having a binding site for a primer. The oligonucleotides that correspond to the end oligonucleotides of the desired sequence also have a universal 3′ flanking sequence and a universal 5′ flanking sequence, respectively. The methods involve performing a first amplification reaction on the plurality of pairs of oligonucleotides; removing the 3′ and 5′ primer binding sequences from the plurality of pairs of oligonucleotides; and subjecting the plurality of pairs of oligonucleotides to an assembly reaction to thereby assemble the dsDNA molecule having the desired sequence.

摘要: The present invention relates to improved semi-automated methods that permit the extraction of nucleic acids from samples, preparation of PCR and post-PCR preparation steps of DNA- libraries for next-generation sequencings methods that can be conducted. The methods and additional aspects relating to such methods are less laborious, safe costs, reagents and are less prone to contamination than comparable methods that are not automated.

摘要: A method for producing genetically engineered immune cells, e.g. T cells, or iPSCs which uses an RNA-scaffold mediated base editing system. The method enables precise modifications to be made to the genome whilst minimizing the possibility of off-target effects, making the method particularly suitable for therapeutic applications.

摘要: A recombinant vector of a thermolabile UNG fused protein and an expressing and purifying method are provided. The method comprises cloning a Cod UNG genetic sequence to a pCold-SUMO vector to construct a recombinant vector pCold-SUMO-Cod UNG, transforming to E. coli BL21 (DE3) competent cells, transforming and expressing molecular chaperone plasmids pG-Tf2, and inducing the expression at a low temperature to obtain a soluble SUMO-Cod UNG fused protein.

摘要: The present invention provides a method of modifying a targeted site of a double stranded DNA, including a step of contacting a complex wherein a nucleic acid sequence-recognizing module that specifically binds to a target nucleotide sequence in a selected double stranded DNA and DNA glycosylase with sufficiently low reactivity with a DNA having an unrelaxed double helix structure (unrelaxed DNA) are bonded, with the double stranded DNA, to convert one or more nucleotides in the targeted site to other one or more nucleotides or delete one or more nucleotides, or insert one or more nucleotides into the targeted site, without cleaving at least one strand of the double stranded DNA in the targeted site.

摘要: Sequential assembly of oligonucleotide hairpins is used to create oligonucleotides with specific sequences. Each oligonucleotide hairpin includes a payload region containing one or more nucleotides that are added to the end of an anchor strand. Overhang regions on the oligonucleotide hairpins hybridize to anchor strands attached to a substrate. The hybridized oligonucleotide hairpins are covalently attached to the anchor strands by the activity of ligase. The oligonucleotide hairpins include an enzyme cleavage region which, when cleaved, separates the payload region from the remainder of the oligonucleotide hairpin. The oligonucleotide hairpin is separated from the anchor strand by denaturation and washed away. This process is repeated with additional oligonucleotide hairpins to add additional nucleotides to the ends of the anchor strands. A microelectrode array may be used to control the location of hybridization and create multiple oligonucleotides in parallel. Fully assembled oligonucleotides can be separated from the substrate and stored.
