Method and kit for analysis of drug resistance of tumor cells

The present invention discloses a method for analysis of drug resistance of tumor cells. The method includes the steps of: (a) providing silicon dioxide nanoparticles, polystyrene-co-polyacrylic acid nanoparticles or metal-organic framework nanoparticles; (b) co-incubating the silicon dioxide nanoparticles, the polystyrene-co-polyacrylic acid nanoparticles or the metal-organic framework nanoparticles with the tumor cells; and (c) detecting endocytosis of the silicon dioxide nanoparticles, the polystyrene-co-polyacrylic acid nanoparticles or the metal-organic framework nanoparticles by the tumor cells. The analysis method of the present invention can analytically identify drug-resistant tumor cells in a clear, intuitive and efficient way. The provided nanoparticles feature simple synthesis processes that take short periods of time, and after they are co-incubated with the tumor cells, a flow cytometer is used for detection. Based on a result of the detection, a degree of drug-resistance of the tumor cells and a proportion of drug-resistant cells therein are determined, making the method simple and efficient.

20170128593 · 2017-05-11 ·

The present invention relates to an immunostimulatory nanocomplex. The immunostimulatory nanocomplex comprises polyglutamic acid (PGA), a first positively charged substance, a second positively charged substance and a dengue viral protein for holding the dengue viral protein inside. The immunostimulatory nanocomplex is characterized by having a nonuniformally and positively charge distribution along a radial direction thereof. The nonuniformally and positively charge distribution comprises a first electrically charged portion having substantially electrical neutrality, a second electrically charged portion surrounding the first electrically charged portion, and a third electrically charged portion surrounding the second electrically charged portion. The third electrically charged portion has a third volume charge density more than a second volume charge density of the second electrically charged portion, thereby enhancing CD8(+) T-cell response and higher antibody titer after administrating an organism with the immunostimulatory nanocomplex.
