What is SPADE?

What is SPADE?

SPADE (Spanning-tree Progression Analysis of Density-normalized Events) is a way to automatically identify populations in multidimensional flow cytometry data files. SPADE clusters cells into populations and then projects them into a tree like the one shown below. SPADE works for data from both ‘classic’ fluorescence flow cytometry and mass cytometry.

The SPADE tree above shows CD14 expression in different cell populations in human bone marrow. To read more about SPADE, look up the mass cytometry study recently published in Science from Garry Nolan’s lab at Stanford and DVS Sciences, now a Fluidigm Company.
