壓電細胞微管吸吮系統(tǒng)

計算機控制的全自動微吸管系統(tǒng)

該系統(tǒng)是一種安裝在正常倒置顯微鏡上的計算機控制的微量吸管系統(tǒng)，

特點：

• 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
