Webbased on size is still lacking. In the context of CyTOF, “event length”, which is generated based on the time taken for the con-tents of ion cloud to “travel,” can be utilized as a crude estimate of the cell size. However, this proxy parameter alone lacks suffi-cient resolution for accurate separation of conventional subsets. WebOct 2, 2024 · For CyTOF, the rate is often closer to 200–300 cells per second, which means that the instrument will need to run for longer to acquire a useful number of data points—especially when running larger samples resulting from barcoding. ...
