TOX21_AutoFluor_HEPG2_Cell_green, is one of 6 assay component(s) measured or calculated from the TOX21_AutoFluor_HEPG2 assay. It is designed to make measurements of artifacts, a form of background reporter, as detected with fluorescence intensity signals by Autofluorescence technology.Data from the assay component TOX21_AutoFluor_HEPG2_Cell_green was analyzed into 1 assay endpoint. This assay endpoint, TOX21_AutoFluor_HEPG2_Cell_green, was analyzed in the positive fitting direction relative to DMSO as the negative control and baseline of activity. 
Using a type of background reporter, gain-of-signal activity can be used to understand changes in the background control. 
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 background control function. 
To generalize the intended target to other relatable targets, this assay endpoint is annotated to the background measurement intended target family, where the subfamily is artifact fluorescence. Is this molecule effective to this assay?
