Clinical Flow Cytometry for the Perplexed-Part 2: Technical Considerations


This lecture covers the technology behind flow cytometry including a very high level overview of how a modern flow cytometer works, how fluorophores work along with their technical limitations such as tandem breakdown, and compensation issues. Also covered an explanation for modern displays of bivariate data, fit for purpose panel design, and more examples compensation artifacts.
