Title:
細胞計測および分離チップ
Document Type and Number:
Japanese Patent JP4601423
Kind Code:
B2
Abstract:
The present invention provides a cell sorting device using an inexpensive chip capable of being exchanged for each sample for cell sorting. The cell sorting device uses flow paths formed on the substrate, including:
a first flow path (204) allowing a buffer fluid containing cells to flow down; second and third flow paths (205,205') which put the first flow path therebetween and allow a buffer fluid not containing cells to flow down from both sides of the first flow path; a fourth flow path (240) which allows the buffer fluid as a single flow path formed by the join of the buffer fluid in the first flow path and the buffer fluid in the second and third flow paths; a cell detecting region (221) for detecting cells flowing with a buffer fluid down the fourth flow path; a cell sorting region (222) for sorting the cells according to a type of the cells detected. The first flow path and the fourth flow path are structured to have substantially the same width or cross-section area.
