Mass cytometry couples highly sensitive ICP-TOF technology with flow cytometry-like high speed single cell analysis
How it works
Cells in suspension are fixed and stained metal-conjugated antibodies. These cells are individually introduced to the ICP (inductively coupled plasma) where they are atomized and ionized to form an ion cloud. Biological elements are filtered out before the ion cloud then passes through the TOF (time-of-flight) chamber where ions are separated by mass and counted. Data is exported into .fcs files for analysis.

Antibodies
Antibodies are conjugated to non-rare, non-biological, non-radioactive isotopes, mostly within the lanthanide series. High isotopic purity combined with proper panel design helps ensure low signal overlap.
