Patent number: 8765370Abstract: A method for screening cells with high level expression of a target protein is disclosed. The method includes introducing into a plurality of host cells a DNA construct that encodes both a target protein and an inhibitor to an endogenous selectable marker in the host cells, screening host cells harboring the DNA construct for the expression of the endogenous selectable marker, and isolating cells with reduced expression of the selectable marker. Also disclosed is a DNA construct configured to express both the target protein and the inhibitor inside the host cell.Type: GrantFiled: June 3, 2010Date of Patent: July 1, 2014Assignee: Scinopharm Taiwan, LtdInventors: Wei-Kuang Liu, Min-Pey Ding

Patent number: 8737044Abstract: A moving module and an electronic device are provided. The electronic device includes a first body, a second body, and the moving module disposed between the first and second bodies. The moving module includes a rail, a moving element, and an elastic element. The moving element is in contact with the rail. The elastic element is connected between the moving element and the first body. When the moving element moves from a first end of the rail to a curved portion of the rail, a force exerted on the elastic element by the moving element is gradually increased. When the moving element passes the curved portion, an elastic restoration force of the elastic element drives the moving element to move toward a second end of the rail. When the moving element reaches the first end or the second end, the first body and the second body interfere with each other.Type: GrantFiled: May 5, 2010Date of Patent: May 27, 2014Assignee: HTC CorporationInventors: Chen-Kuang Liu, Yu-Min Chen, Cheng-Te Chen
