Interrogation of surface receptors of individual cells (30) within a population of cell types in a single mixture is described. Each cell comprises, bound to target surface receptors on the cell, a collection of binding compositions, each comprising a distinct molecular tag. A continuous flow of cell medium containing the cells is pneumatically transported (22) through a channel in a separation device, toward a cleavage/release zone (16), where specific tags correlating to each binding composition, and thus to each corresponding cell surface receptor, are released (34) from the binding compositions on the cell surface. The method is effective to produce a separately detectable collection of tag signals for each cell. |
