Abstract
A method for detecting a target molecule of a structure body, including contacting a dispersion liquid including a structure body with a well array including wells such that the structure body is introduced into the wells, bringing a sealing solution into contact with the well array such that the structure body is sealed in at least one of the wells, extracting a content of the structure body in the well, detecting a surface target molecule present on a surface of the structure body in the well, and detecting an internal target molecule present inside the structure body in the well.
Claims10
A kit for detecting a target molecule of a structure body, comprising:
- a fluid device comprising a substrate containing a well array including a plurality of wells for introduction of a structure body and a dispersion liquid into the wells,
- wherein the fluid device further comprises a cover member on top the substrate and a flow path between the substrate and the cover member, wherein the cover member comprises an inlet port on one end of the flow pass of the fluid device and an outlet port on the other end such that the dispersion liquid upon introduction between the substrate and the cover member through the inlet port is capable to flow downward from the inlet through the flow path over the surface of the well array and enters each well;
- a reagent for extracting a content of the structure body,
- a sealing solution for sealing the dispersion liquid containing the structure body in each wells and displacing the dispersion liquid that is not accommodated in the wells;
- and
- a reagent 1 that detects a surface target molecule that is present on a surface of the structure body, and a reagent 2 that detects an internal target molecule that is present inside the structure body, under same conditions in the same well, wherein the reagents 1 and 2 are signal amplification reaction reagents for detection and amplification signals emitted by the surface target molecule and the internal target molecule by a signal amplification reaction, wherein the emitted signals are different.
