Confocal microscopy to observe both GFP and huCD36 protein expression. Constructs of pEGFP-C3-CD36, pEGFP-N3-CD36, and pEGFP-N3 vector alone, were transit-transfected into CHO cells for 48 hours, and the transfected cells were then immunostained with anti-CD36 antibody, counter-stained with TRIC-conjugated anti-mouse IgG secondary antibody. After washing several times, cells were mounted on slides and observed under confocal microscope. Top panel: pEGFP-N3 transfected alone; Middle panel: cells transfected with pEGFP-C3-CD36; Bottom panel: pEGFP-N3-CD36 transfected. Both GFP and CD36 were expressed in two constructs.
