The beta-2 adrenergic receptor (β2 adrenoceptor); also known as ADRB2, is a cell membrane-spanning beta-adrenergic receptor. beta2 adrenoceptor Assay (ADRB2) from Innoprot allows the measurement of ADRB2 receptor activation using Nomad biosensors technology. beta2 Adrenoceptor signaling occurs via adenylate cyclase stimulation through trimeric Gs proteins, increasing cAMP, and downstream L-type calcium channel interaction. cAMP-Nomad Biosensor measures the receptor activation by cAMP accumulation.
