压电细胞微管吸吮系统

计算机控制的全自动微吸管系统

该系统是一种安装在正常倒置显微镜上的计算机控制的微量吸管系统，

特点：

• 1)High throughput single cell sorting directly from the Petri dish

• One single cell arrives to each PCR tube

• 10 PCR strips containing 80 tubes can be filled in a cycle

• Glass cover slip for testing single cell deposition in situ

• Drop volume less than 1 ul for adherent cells

• Pick up volume of ~1 nl for suspended cells

• 15-20 seconds per cell. When collecting multiple cells, sorting speed is 1 cell/second.

• Number of cells picked up in a single run: 1-1000.

• Isolates a subpopulation of live adherent cells expressing fluorescent or luminescent markers

• Both unlabeled and fluorescentcells are recognized by computer vision

• Viable cells after sorting

• Any adherent and non-adherent cell type can be sorted

• Cell culture needs minimal preparation before sorting

• Average sorting process takes only a few minutes

• Multichannel detection using the fluorescent filter setup of the microscope
