The expression pattern of the CD4 protein between two haplotypes in pigs. a Confocal images of the immune stain of GFP (green) and CD4 (red) proteins. Nucleus was stained with DAPI (blue). Scale bars: 10 μm. b Western blotting results of the CD4-GFP fusion protein at 24 h and 48 h post-transfection using GFP antibody. β-actin was used as internal control
