Tube for measuring bio-related substance and quantifying system
First Claim
1. A quantification system for a bio-related substance, which comprises:
- a bio-related substance assay tube;
a detection unit for detecting signals emitted from microparticles in the tube;
wherein the microparticles comprises;
a first microparticle on which a substance capable of binding to a target bio-related substance to be measured is immobilized, the first microparticle fixed in a first known position in the tube;
a second microparticle on which the bio-related substance is immobilized in a given amount, the second microparticle fixed in a second known position in the tube; and
a third microparticle for use as a negative control, the third microparticle fixed in a third known position in the tube,wherein these microparticles are aligned along the longitudinal direction of the tube, andwherein the detection unit moves relative to the tube along the longitudinal direction of the tube.

Abstract
A bio-related substance assay tube 2 comprises a target substance capture bead 3 serving as a first microparticle, compensation bead 4 serving as a second microparticle on which a given amount of a bio-related substance has been immobilized, and a negative control bead 5 serving as a third microparticle for use as a negative control. A mount unit 12 comprises a nozzle communicating with a pump, and the bio-related substance assay tube 2 is mounted in the mount unit 12 to ensure communication with this nozzle. An analyte is introduced into the bio-related substance assay tube 2, followed by labeling the bio-related substance bound to each microparticle to cause light emission. Based on light emission from each microparticle, a calibration curve is prepared or the emission intensity of the first microparticle is compensated to quantify the bio-related substance.
