  • NOVEL PLURIPOTENT CELLS
    Publication number: 20240252551
    Abstract: The present invention relates to: a method for converting non-pluripotent cells into pluripotent cells; cells produced by the method; and uses thereof. The pluripotent cells of the present invention have low tumorigenicity while having excellent cell differentiation ability and pluripotency capable of differentiating into three germ layers, and can specifically separate pluripotent cells in the intermediate stage of reprogramming, and thus, it is possible to produce pluripotent cells having characteristics different from conventional induced pluripotent stem cells.

  • PNA chip using plastic substrate coated with epoxy group-containing polymer, method of manufacturing the PNA chip, and method of detecting single nucleotide polymorphism using the PNA chip
    Patent number: 7696130
    Abstract: Provided is a PNA (Peptide Nucleic Acid) chip in which a probe PNA containing a desired DNA sequence is immobilized on a plastic substrate coated with an epoxy group-containing polymer. Therefore, single-stranded PNAs can be immobilized on a transparent plastic substrate by means of an epoxy group-containing polymer layer in an efficient and cost-effective manner. Fluorescence signal detection based on PNA/DNA hybridization enables identification of SNP (Single Nucleotide Polymorphism).
