Abstract: Provided are a composition and a kit, each for culturing natural killer cells, and a method of using the same. According to the composition for culturing natural killer cells according to aspect, and a method of culturing natural killer cells using the same, when natural killer cells are cultured in peripheral blood mononuclear cells, they are cultured in a medium including the composition for culturing natural killer cells, the composition including magnetic particles, of which at least one surface is bound with an activating receptor ligand, an inhibitory receptor ligand, a costimulatory receptor ligand, a cytokine, a cytokine receptor, an immune checkpoint ligand, a blocking antibody, or a combination thereof, thereby proliferating natural killer cells in a large quantity and promoting activation or inhibition of natural killer cells, or expansion of natural killer cells. Accordingly, the natural killer cells cultured using the same may be usefully applied to immune cell therapy products.

Abstract: A tissue product comprising an additive composition onto at least the surface of a fibrous article in order to increase the surface potential of the article, while retaining or improving manufacturing efficiency is disclosed. The additive composition comprises a bacteriostatic component and more preferably a water-soluble adhesive component and a bacteriostatic component. In some aspects, the additive may also contain additional water-soluble modifier components. Tissue products according to the present disclosure can attract and trap negatively charged matter, such as bacteria, into the tissue web. As such, tissue products can pickup bacteria from a surface and substantially hold the bacteria in the sheet to help prevent spreading bacteria to other surfaces.
