Fig. 4From: Infrared-emitting, peptidase-resistant fluorescent ligands of the bradykinin B2 receptor: application to cytofluorometry and imagingImaging of intact HEK 293 stably expressing or not B2R-GFP based on the Cy7-conjugated antagonist ligand B-10665 (infrared fluorescence rendered as the red false color). All labelings were performed for 30 min at 37 °C, followed by rinsing. Original magnification 95×Back to article page
