Abstract
Aspects of the present disclosure include methods that include co-culturing a cell and a microparticle that includes a capture ligand, in a culture medium under conditions in which a biomarker produced by the cell is bound by the capture ligand. Such methods may further include detecting (e.g., by flow or mass cytometry) complexes that include the microparticle, the capture ligand, the biomarker, and a detection reagent. The methods may further include determining the proportion or number of cells among a heterogeneous cell population that produced the biomarker and/or the level of biomarker secreted by such cells. Compositions, systems and kits are also provided.
