20110245456 | BIODEGRADABLE POLYMER MICROPARTICLES AND PREPARATION METHOD THEREOF - The present invention relates to a preparation method for a biodegradable polymer microparticle and a microparticle prepared by the method. More particularly, the present invention relates to a method for preparing a polymer microparticle, wherein the method includes the steps of: dissolving a biodegradable polyester-based polymer in DMSO (Dimethyl Sulfoxide); spraying the solution in a low temperature hydrocarbon solution to provide a frozen DMSO microparticle; adding the microparticle in a low temperature salt aqueous solution to dissolve DMSO; and removing salt. The present invention provides a method for preparing a novel polymer microsphere which can be injected through a syringe due to excellent physical properties (such as biocompatibility, biodegradability, porosity, mechanical strength) and the microcarrier's size-adjustability, and can be easily mass-produced. The microparticle prepared by the method of the present invention may have variable sizes with biodegradability and biocompatibility, and thus can be used as a carrier for regeneration of a damaged cell or tissue by being injected into a body through a syringe. | 10-06-2011 |
20090068189 | Monoclonal Antibody to Human TGF-Beta Induced Gene-H3 and Use Thereof - The present invention relates to a monoclonal antibody to human βig-h3 and the use thereof. More particularly, it relates to a monoclonal antibody to the human βig-h3 protein, wherein the epitope of the monoclonal antibody is the H1 region of the fourth fas-1 domain of the human βig-h3 protein. The monoclonal antibody can specifically recognize the human βig-h3 protein in tissue, and so will be useful in diagnosing a disease associated with the increase or decrease of the βig-h3 protein. In addition, the monoclonal antibody has the effect of inhibiting the cell adhesion activity of the βig-h3 protein. | 03-12-2009 |
