We live in an era of data-driven science in which we can sequence the genomes of individual cells and measure the full complement of proteins contained within. How do we acquire and measure such data? The vast world of the “-omics,” including genomics and proteomics, has become accessible to research scientists in basic and clinical research sectors because of the rise of new tools and techniques that have improved the speed, accuracy, and affordability of the methods. Flow cytometry has been a critical technique in this revolution as it allows for the detection and sorting of individual cells. Check out the main features of each of these “-omics” fields and how they complement your current research projects.
