Flow cytometry is a powerful tool in drug discovery because it provides a way to understand the drug’s mechanism of action. In order to stratify a better target for patients, you often need to know where the drug is working, and what kind of pathway it is operating along.

The combination of simplicity and power is turning flow cytometry into the highest throughput protein analysis method yet developed.
Large-scale protein analysis, or proteomics, is still a relatively small discipline where the research front is driven by a few labs with unrestricted access to mass spectrometry (MS). MS is equivalent to a mainframe computer: very big, very sophisticated, and only a few people have the skills to use them.

One of the frustrations I have with Flow Cytometry is when companies present their amazing new findings at conferences, and it’s quite often about TMB cells. In my case, I work on these cells perhaps 20% of the time. The rest of the time I work on cells from other parts of the human body – bone marrow, lung, bronchoalveolar lavage, spleen – and in diverse animals such as mice, rats, and even sparrow, chicken, and mosquito.

The ability to measure multiple forms of cell death simultaneously represents a significant development for such techniques. I have been using antibodies and more specific forms of dyes to identify mitochondrial activity and reactive oxygen in roughly fifty populations, whereas normally it would only be able to measure one at a time. I will be discussing this work at the Flow Cytometry Congress, and it could prove enormously beneficial to drug and immunotherapy development.
