Profile heterogeneity in your samples by measuring protein expression in thousands of single cells in a single run. All you need to do is load your cell suspension. The scWest chip captures ~1,000 single-cells. Once everything is ready, Milo performs a fast, 1 minute SDS-PAGE separation on each single-cell lysate on-chip. Finally, probe with your favorite conventional Western antibodies to measure ~12 proteins per cell using a variety of multiplexing strategies.
