Abstract: Provided is a peptide containing a variable region and improved in production efficiency. The peptide contains a variable region to which an antigen-binding site is to be formed and has an amino acid sequence expressing a specific adsorption function to a solid phase at a site closer to the C-terminal than a heavy-chain variable region or at a site closer to the C-terminal than a light-chain variable region.

Abstract: A fluid handling apparatus 10 has a plurality of fluid handling subassemblies 16, each of which is mounted in a corresponding one of mounting recessed portions 14 of a plate body 12. Each of the fluid handling subassemblies 16 includes: an injecting section 26 for injecting a fluid; a fluidized section 28 for receiving the fluid from the injecting section 26 to allow the fluid to continuously flow downwards; a fluid housing chamber 30 for receiving the fluid from the fluidized section 28; a wall portion 20 formed so as to extend in substantially vertical directions between the fluid housing chamber 30 and the fluidized section 28; an opening 20a for allowing the fluid in the fluidized section 28 to enter the fluid housing chamber 30; and a surface-area increasing means (22, 32, 34) for increasing the area of a contact surface with the fluid in the fluidized section 28.

Abstract: There is provided a container with lid capable of preventing evaporation of a liquid, which is stored in the container, even if the liquid is continuously pipetted from the container. The container 10 with lid has a tubular container body 12 having a bottom 12b at the lower end thereof and having an opening 12a at the upper end thereof, a first lid portion 14 for opening and closing the opening 12a of the container body 12, a second lid portion 16 for opening and closing an opening 14a which is formed in the first lid portion 14, a first connecting portion 18 which connects the first lid portion 14 with the container body 12, and a second connecting portion 20 which connects the second lid portion 16 with the first lid portion 14, wherein the container body 12, the first and second lid portions 14, 16, and the first and second connecting portions 18, 20 are integral-molded. A first sealing member 22 is mounted on the first lid portion 14, and a second sealing member 24 is mounted on the second lid portion 16.

Abstract: There is provided a sample analyzing apparatus capable of simply and rapidly carrying out each step of electrophoresis, transfer and detection to analyze a substance, such as a biosubstance, in a sample. By sticking an upper plate member 14 to a lower plate member 12 having a fine groove 12a, an electrophoresis passage 13 is formed in the apparatus. A pair of separating electrodes 18 and 20 are provided for moving a substance, such as a biosubstance, along the electrophoresis passage 13 by electrophoresis, and a pair of transferring electrodes 16 and 22 are arranged in the electrophoresis passage 13 for transferring the substance to a capturing material 24 by electrophoresis.
