_MPXNOMAD Cells are cell lines stably co-expressing tag-free GPCRs and two Nomad Biosensors to monitor G-protein and β-arrestin modulation. Each vial of _MPXNOMAD α1B-adrenoceptor Cell Line contains HEK293 cells stably expressing the following constructs:

• human α1B-adrenoceptor with no tag
• Calcium Nomad Biosensor (Green Fluorescence)
• β-arrestin Nomad Biosensor (Red Fluorescence)

_MPXNOMAD α1B-adrenoceptor Cell Line allows to assay compounds analyzing both signalling pathways involving receptor activation; G protein by Calcium flux and β-arrestin recruitment, hence allowing biased activity studies. When an agonist binds to ADRA1B a G protein is activated which, in turn, triggers a cellular response mediated by calcium and a subsequent internalization mediated by ß-Arrestin. This leads to an increase of fluorescence intensity of both β-Arrestin and Ca²⁺ biosensors. So, the activity can be easily quantified on living cells in a dose-response manner by fluorescence emission in a microplate reader.
