  • Patent number: 8999673
    Abstract: Provided is a method for selectively obtaining, for a given target gene, a “joined DNA fragment” wherein just a target gene fragment is joined with desired other DNA fragments, regardless of whether a DNA fragment containing a target gene sequence has been purified. In the provided method, a double-stranded joining DNA fragment containing a sequence A and/or a sequence B is selectively joined to the ends of a target gene fragment. A mixture of a double-stranded gene fragment, the 3? end of which is protruding, and the double-stranded joining DNA fragment, which are related in a prescribed manner, undergoes at least two cycles of thermal denaturation, reassociation, and DNA synthesis, resulting in a “joined DNA fragment,” which is a double-stranded DNA fragment including at least one instance of a sequence resulting from joining sequence A, the target gene sequence, and sequence B. A “single-side joined DNA fragment” can also be obtained, by a similar method.

  • Patent number: 8980579
    Abstract: Provided herein are methods for stable integration and/or expression of one or more recombinant polynucleotides in a host cell. The recombinant polynucleotides are typically integrated into the host genome at some native chromosomal integration sites. The integration can be mediated by homologous recombination or by using a hybrid recombinase targeting the specific chromosomal locations. The native chromosomal integration sites in the host cells, which support stable integration and strong transcription activities of foreign genes, are present within or adjacent to specific genes in the CHO genome, the ankyrin 2 gene (Ank2), cleavage and polydenylation specific factor 4 gene (Cpsf4), C-Mos gene, and Nephrocystin-1/Mal gene. Also provided are methods and nucleic acid molecules for inserting site-specific recombination sequences (chromosomal landing pads) into these specific chromosomal locations, engineered host cells containing chromosomal landing pads, methods and compositions (e.g., kits) therefore.

  • Patent number: 8859229
    Abstract: A method of mRNA production for use in transfection is provided, that involves in vitro transcription of PCR generated templates. This RNA can efficiently transfect different kinds of cells. This approach results in increased efficiency (fidelity and productivity) of mRNA synthesis and is less time consuming because it does not require cloning, and also consequently eliminates the unwanted errors and effects related to RNA made on DNA templates obtained with cloning techniques. The results of transfection of RNAs demonstrate that RNA transfection can be very effective in cells that are exceedingly difficult to transfect efficiently with DNA constructs. The method can be used to deliver genes into cells not- or only poorly transfectable for DNA, in vitro and in vivo.
