BSK_3C_uPAR is an assay component measured in the BSK_3C assay. It measures uPAR antibody related to regulation of gene expression using ELISA technology.Data from the assay component BSK_3C_uPAR was analyzed into 2 assay endpoints. This assay endpoint, BSK_3C_uPAR_down, was analyzed in the negative fitting direction relative to DMSO as the negative control and baseline of activity. 
Using a type of binding reporter, loss-of-signal activity can be used to understand changes in the signaling as they relate to the gene PLAUR. 
Furthermore, this assay endpoint can be referred to as a primary readout, because this assay has produced multiple assay endpoints where this one serves a signaling function. 
To generalize the intended target to other relatable targets, this assay endpoint is annotated to the "cytokine" intended target family, where the subfamily is "plasmogen activator". Is this molecule effective to this assay?
