Abstract: A bag supply method includes the steps of: causing an arrangement device to arrange a bag at a pickup position; delivering the bag from the pickup position to a support device via a bag pickup device; moving the bag along with the support device in a traveling direction along a movement path including a detection position; determining arrival of the bag at the detection position; stopping the bag along with the support device on the movement path according to a timing when the bag arrives at the detection position; and delivering the bag stopped in the movement path, from the support device to a bag receiving device via a bag holding conveyance device.

Abstract: Monoclonal antibodies having a high affinity for human calcitonin, particularly monoclonal antibodies suitable for a sandwich immunoassay are disclosed. Also disclosed are hybridomas producing said monoclonal antibodies and a sandwich immunoassay utilizing said antibodies for determining human calcitonin in blood.

Abstract: A monoclonal antibody specifically recognizing N-terminal portion of human calcitonin (hCT), a hybridoma producing said monoclonal antibody, a process for preparing said monoclonal antibody, and a method for detecting hCT which comprises the use of said monoclonal antibody are provided.The above monoclonal antibody permits detection of hCT with high sensitivity.
