Mass Cytometry: Vaporizing Cells in the Name of Science

Mass cytometry, a technique developed by DVS Sciences, represents a revolutionary spin on classic fluorescence-based flow cytometry. Instead of using antibodies tagged with fluorophores (in which spectral overlap quickly limits the number of parameters available for simultaneous detection), mass cytometry relies on antibodies tagged with transition element isotopes. Antibody-bound cells are vaporized, ionized, and analyzed on a mass spectrometer.

Biochemistry at the Single Cell Level

Dataset #811: 090902-PBMC stim with IL6, IL10, LPS (Public Version)

Western blots are great. That is, unless you’re studying signal transduction in a mixed population of primary cells. The amount of material necessary for many biochemical techniques is usually not practical when working with patient samples or rare cell populations.

Flow cytometry to the rescue! Phospho-flow tracks biochemistry at the single cell level. Simultaneous assessment of cell surface markers and signaling events for individual cells enable biologists to profile disease samples or monitor the effects of drugs in clinical samples. (more…)
