Fig. 2From: Label-free and washing-free alkaline phosphatase assay using a personal glucose meterDetection feasibility of the PGM-based ALP assay. The PGM signals from different samples containing ATP only (a), both ALP and ATP (b), and neither ALP nor ATP (c). The concentrations of ALP and ATP were 400 U/L and 1 mM, respectivelyBack to article page
