  • Method for separating, capturing, analyzing and retrieving cells and cell products by using microstructure
    Patent number: 11692191
    Abstract: The present invention relates to a technique for genomic library screening and provides a method for separating, capturing, analyzing, and retrieving cells and cell products by using a microstructure that can be preferentially applied to the field of antibody engineering for the development of new therapeutic antibodies and can be extensively applied to multiple genetic/phenotypic analysis of various biochemical molecules, for example, in the field of protein engineering and metabolic engineering.
    Type: Grant

  • Thermoplastic resin composition and article produced therefrom
    Patent number: 11492487
    Abstract: A thermoplastic resin composition and a molded article formed of the same. The thermoplastic resin composition includes: about 100 parts by weight of a polycarbonate resin; about 5 to about 20 parts by weight of a rubber modified aromatic vinyl copolymer resin; about 0.5 to about 3 parts by weight of a maleic anhydride-grafted rubber polymer; about 50 to about 100 parts by weight of glass fibers; about 10 to about 30 parts by weight of barium sulfate; and about 5 to about 20 parts by weight of a phosphorus flame retardant. The thermoplastic resin composition can have high specific gravity and good properties in terms of impact resistance, weather resistance, flame retardancy, fluidity, and the like.
