20090098541 | Devices and processes for analysing individual cells - A device for individually analysing cells of interest, comprising (a) a channel for receiving the contents of a cell of interest, wherein the channel has an input end and an output end, and (b) a cell trapping site in proximity to the input end of the channel, wherein (i) the input end of the channel is adapted such that an intact cell of interest cannot enter the channel; and (ii) the channel contains one or more analytical components for analysing the contents of the cell of interest. In use, a cell is applied to the device, where it is trapped by the cell trapping means. The cell cannot enter the channel intact, but its contents can be released in situ to enter the channel's input end. The contents can then move down the channel, towards the output end, and they encounter the immobilised reagents, thereby permitting analysis of the cell contents. | 04-16-2009 |
