計(jì)算機(jī)控制的自動(dòng)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(jì)算機(jī)控制的微量吸管系統(tǒng)，量化細(xì)胞形變、細(xì)胞間粘附作用和細(xì)胞與基質(zhì)之間的粘附作用，可同步實(shí)現(xiàn)熒光觀測(cè)、單細(xì)胞捕獲、分選和分離和圖像視頻處理

一個(gè)可在已有顯微鏡上搭建的，可同步實(shí)驗(yàn)吸吮加載、圖像視頻處理與熒光觀測(cè)的細(xì)胞力學(xué)裝置。可建立微管吸吮力學(xué)加載-熒光觀測(cè)耦合的分子-細(xì)胞動(dòng)力學(xué)實(shí)時(shí)原位觀測(cè)系統(tǒng)。

特點(diǎn)：

• 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
