TOX21_ARE_BLA_Agonist_viability is an assay readout measuring cellular ATP content and detected with CellTiter-Glo Luciferase-coupled ATP quantitation.TOX21_ARE_BLA_Agonist_viability used a type of viability reporter where loss-of-signal activity can be used to understand changes in the cell viability. Furthermore, this assay endpoint can be referred to as a secondary readout, because this assay has produced multiple assay endpoints where this one serves a viability function. To generalize the intended target to other relatable targets, this assay endpoint is annotated to the cell cycle intended target family, where the subfamily is cytotoxicity. Is this molecule effective to this assay?
