  • Patent number: 11946651
    Abstract: A portable air flow apparatus may include a base configured to be seated on a surface, a head comprising a suction inlet through which air is suctioned into the head and a discharge outlet through which the air suctioned in through the suction inlet is discharged, the suction inlet and the discharge outlet being horizontally spaced apart from each other at a right angle with respect to a vertical direction, and a column that connects the head and the base in such a manner that the head is vertically spaced from the base.

  • Patent number: 11884750
    Abstract: A cell penetrating peptide (CPP) according to the present invention is a novel cationic cell penetrating peptide that can effectively transport a biologically active molecule by passing through a cell membrane even when a biologically active molecule is bound thereto, and compared with conventional CPPs, it has excellent cell permeability enabling the transport of a biologically active molecule into cells, and the delivered biologically active molecule may effectively maintain its activity in cells. Accordingly, the CPP of the present invention may be very useful in various fields including cosmetics, diagnostics, drug delivery systems, recombinant protein vaccines, DNA/RNA therapeutics, and gene and protein therapy.

  • Publication number: 20220112514
    Abstract: The disclosure in the specification relates to an artificial recombinant chromosome and the use thereof, and more particularly to an artificial recombinant chromosome generated by the recombination of two or more chromosomes and a production of a transgenic animal using a cell including the same. Especially, in the disclosure in the specification, an interchromosomal exchange between the recipient chromosome and the donor chromosome has many merits to produce the artificial recombinant chromosome for producing the transgenic animal.

  • Publication number: 20220033781
    Abstract: An artificial recombinant chromosome produced by recombination of two or more chromosomes and the production of a transgenic animal using a cell including the same are disclosed. A method for producing a cell including one or more artificial recombinant chromosomes includes preparing a first targeted cell and a second targeted cell, producing one or more microcells using the second targeted cell, producing a fusion cell using the first targeted cell and the one or more microcells, and producing a cell including an artificial recombinant chromosome by treating the fusion cell with site specific recombinase (SSR).

  • Publication number: 20210400934
    Abstract: A transgenic animal having a genome including a humanized immunoglobulin locus for securing the diversity of an antibody repertoire and a method of producing the same are disclosed. The transgenic non-human animal has two alleles of a humanized immunoglobulin gene, wherein the two alleles are hetero-alleles.
