Title: Immunoassay enhanced in sensitivity
Inventor: NAKAJIMA TAZUKO
IPC: G01N33/543
Filed: 1994-06-07
Abstract: PURPOSE:To enhance the measuring sensitivity of immunoreaction due to multistage reaction by repeatedly performing the formation of an immune composite containing an object to be measured held to the same solid phase and the separation (B/F separation) operation of a bound label and a free label to cumulatively increase the amt. of the composite. CONSTITUTION:An immune composite consisting of an insolubilized first immune substance and a specific substance is formed by performing incubation along with a solid phase to which a first immune substance specifically reacting with the antibody or antigen (specific substance) to be measured in a fluid sample is bonded and the solid phase having the immune composite bonded thereto is separated from the reaction mixture. An immune composite composed of an insolubillzed immune substance is newly formed by incubating a newly prepared fluid sample along with a solid phase and separated from the reaction mixture having the immune composite held thereto. By repeating this process, the immune composite containing a substance to be measured is cumulatively increased on the solid phase. By this constitution, the amt. of the immune composite held on the solid phase, that is, the absolute amt. of the substance to be measured is cumalatively increased and detection sensitivity is enhanced.

Filed: 1991-06-24
Abstract: PURPOSE:To enhance yield while maintaining the performance of a printing head and realize a low-cost and stable production by bonding a conductive substrate on a part of a piezoelectric element using an insulating adhesive. CONSTITUTION:The full surface of a piezoelectric element 1 serving as a vibration source is bonded to a conductive film 4 of a vibration plate 5 as a component of a flow path through an adhesive layer 20.
