Figure 7
No change in DRD3 and DRD4 protein levels upon hypoxia. 48-hour hypoxic (1% O2) or control (21% O2) SK-NF-I and CCF-STTG1 cultures were immunostained with anti-DRD3 (1:50) or anti-DRD4 (1:250) antibodies, respectively. Representative images from three independent experiments (N = 3) are shown. The first column displays backgrounds obtained by omitting the primary antibody from the staining assays.
