Figure 1From: Characterization of a panel of six β2-adrenergic receptor antibodies by indirect immunofluorescence microscopyAb-Bethyl Specifically Recognizes Human β 2 AR in HEK 293 Cells. HEK 293 cells stably expressing human β2AR (A, B) and HEK 293 cells transiently expressing rat β2AR (C, D) were either untreated (A, C) or treated (B, D) with isoproterenol for 4.5 h in parallel, fixed and processed for microscopy (Axioskop 2 plus epifluorescent microscope).Back to article page
