ALP activity was determined following the manual instructions of ALP assay kit (Abcam plc, Cambridge, UK). The color of the reaction was measured at 405 nm. The number of viable cells was determined using the Cell Titer-Blue cell viability assay according to the manufacturer’s instructions (Promega, USA) at OD 579. ALP activity was represented as fold change over control non-induced cells after normalization to the number of viable cells [40 (link)].
