The assay studied the role of the relaxin hormone in biological processes, including extracellular matrix remodeling and tissue homeostasis, and evaluated the potential therapeutic applications of recombinant human relaxin. The study used a HEK293T cell line with RXFP1 to screen for agonists of the relaxin receptor and detected RXFP1 activation through changes in cAMP levels using a TR-FRET cAMP detection kit. Is the molecule effective to this assay?
