Recombinant HEK293 cell line stably expressing full-length human Calcitonin receptor-like receptor (CALCRL/CRLR/CLR; accession number: NM_005795) and containing a firefly luciferase gene under the control of multimerized cAMP response element (CRE). This cell line can be used to measure the EC50 and IC50 of CALCRL agonists and antagonists using the luciferase reporter activity.
