To provide a microchip that is easily handled. Provided is a microchip having a plate shape and including: a sample liquid inlet into which a sample liquid is introduced; a main flow path through which the sample liquid introduced from the sample liquid inlet flows; and a sorting flow path into which a target sample is sorted from the sample liquid, in which the sample liquid inlet and a terminal end of the sorting flow path are formed on a same side surface. Furthermore, a sample sorting kit including the microchip is also provided. Moreover, a microparticle sorting device on which the microchip is mounted is also provided.

Microchip, sample sorting kit, and microparticle sorting device

To provide a method of efficiently performing priming on a microparticle sorting microchip. The present technology provides a priming method of a microparticle sorting microchip provided with a sample liquid flow path, a sheath liquid flow path that joins the sample liquid flow path at a junction, a joined flow path including the junction at one end, a microparticle recovery flow path connected to the joined flow path via a connection flow path at the other end of the joined flow path, a branching flow path connected to the joined flow path at the other end of the joined flow path, and an introduction flow path configured to introduce a liquid into the connection flow path, the method provided with a first priming step of supplying a first liquid from the introduction flow path to the connection flow path, and performing priming on the microparticle recovery flow path by the first liquid, and a second priming step of allowing a second liquid to flow from the sheath liquid flow path to the joined flow path, and performing priming on the branching flow path by the second liquid.
