We developed a simple, rapid and cost-effective enzymatic-based cytometry platform to measure intracellular signaling pathway activity. Our single-cell microwell array platform quantifies protein phosphorylation using enzymatic signal amplification and exploiting Michaelis-Menten kinetics. Our method provides a two-fold increase in resolution compared to conventional flow cytometry.
