Patent number: 10401322Abstract: A separation unit is a configuration that is arranged vertically, and thus bubbles generating from the electrode will not negatively influence the contact location between the transfer membrane and separation unit. An anode (32) is arranged at a position separated by a certain distance in the conveying direction (X) of the transfer membrane (1) from the dispensing part (50a) of an electrophoresis gel chip (50). An insulating electrode cover (35) for setting free bubbles generating from the anode (32) is arranged at an upper part of the anode (32).Type: GrantFiled: December 8, 2015Date of Patent: September 3, 2019Assignee: Merck LTD.Inventors: Taiga Tominaga, Hideki Kinoshita, Shinichi Goto, Mieko Hirabayashi, Kouhei Kageyama, Takateru Matsunaga, Kimihiko Yabe

Publication number: 20070281366Abstract: A mixture of one or more target molecules and functional monomers having functional groups, which are able to interact with the target molecules, is polymerized so as to form a target molecule recognition polymer (MIP) complex to which target molecules are bound, and a functional group which is contained in the MIP complex but is not bound to the target molecule is deactivated. This makes it possible to suppress binding of a non-target molecule that can be bound to the MIP by weak interaction. Thus, it is possible to provide an MIP exhibiting a high selectivity even when high molecular weight molecules like biomolecules are used as the target molecules.Type: ApplicationFiled: March 15, 2007Publication date: December 6, 2007Inventors: Yuichiro Shimizu, Takateru Matsunaga
