  • Patent number: 11026876
    Abstract: The present invention relates to a composition for skin improvement containing at least one chemokine selected from the group consisting of B lymphocyte chemoattractant (BLC), also known as C-X-C motif ligand 13 (CXCL13), and thymus-expressed chemokine (TECK), also known as C-C motif ligand 25 (CCL25), as an active ingredient. Since the BLC (CXCL13) and TECK (CCL25) of the present invention increase the expression of proliferation marker Ki-67 and collagen IV, which are proteins concerning skin regeneration and skin elasticity, and exhibit excellent melanin-reducing and wound-healing effects and the ability to induce chemotaxis of keratinocytes, they can be applied in a cosmetic composition for skin improvement.

  • Publication number: 20210096080
    Abstract: Disclosed is a test strip for detecting microalbumin in urine, and more particularly a test strip for detecting microalbumin in urine that contains a synthetic albumin indicator, a buffer solution, a surfactant and a polymer (sensitizer) and thus exhibits high sensitivity. The albumin detection test strip has accuracy sufficient to enable clear observation of color change from colorless to blue through the albumin indicator, and improves the detection limit (increases sensitivity) to thereby enable detection of microalbuminuria at a concentration of 20 mg/L or less. The albumin test detection strip contains a surfactant and a polymer in addition to a synthetic albumin indicator, thereby incorporating separate first and second processes into a single process and having effects of reducing costs, improving processing convenience, and increasing solubility and miscibility.

  • Publication number: 20200108096
    Abstract: A method for culturing natural killer cells uses genetically modified T cells. The method for culturing natural killer cells, using genetically modified T cells enables the effective proliferation and production of natural killer cells from a smaller amount of source cells. In addition, the method enhances the cytolytic activity of natural killer cells. Therefore, the method for culturing natural killer cells, using genetically modified T cells may be suitable for various applications in commercializing cell therapy products. Further, the natural killer cells produced by the culturing method can be useful as a cell therapy product.
