TOX21_VDR_BLA_Agonist_viability, is one of 2 assay component(s) measured or calculated from the TOX21_VDR_BLA_Agonist assay. It is designed to make measurements of ATP content, a form of viability reporter, as detected with bioluminescence signals by CellTiter-Glo Luciferase-coupled ATP quantitation technology.TOX21_VDR_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?
