  • Complex of labeled probes and water-soluble carrier
    Patent number: 9005910
    Abstract: The purpose is to produce, with high reproducibility, a complex of labeled probes and a carrier, said complex being to be used for detecting and measuring a target substance to be measured with high sensitivity and high stability. The means for accomplishing the purpose is that a label is bound to a probe-water soluble carrier conjugate using specific binding of an avidin compound such as avidin, streptavidin, etc. to biotin, and the binding of the avidin compound to the probe is performed before the binding to the carrier. Namely, after conjugating the avidin compound to a substance which is capable of binding to the target substance, the conjugate is bound to a high-molecule water-soluble carrier to produce a complex of the avidinized probes and the water-soluble carrier. Then the complex of the avidinized probes and the water-soluble carrier is mixed with a biotinylated label.
