Using Flow Cytometry in Biomedical Science

By Kate Warde (@girlinthelab) Flow cytometry is a common laser technique scientists use to look at the characteristics of each single cell in a large population of cells. How flow cytometry works In flow cytometry, cells are labeled with fluorescent tags that correspond to a specific target; for instance, if we want to look at protein X on a cell, we add a tag that binds to this protein. When the cells run through the cytometer, they are contained in a liquid that flows in single file so that each…

Flow Cytometry: Going with the Flow

By Cathy Seiler @cyc55 Sara Bowen, PhD, is a biochemist with what can only be described as a giddy excitement for her job. She runs the flow cytometry facility at St. Joseph’s Hospital and Barrow Neurological Institute in Arizona, and she positively lights up when talking about “flow” and her lasers. An analogy to understand flow cytometry is to think about a stream filled with lots of different fish: big fish and small fish, black fish and white fish. To better understand the characteristics of the fish in the stream,…
