For western blot analysis: mouse monoclonal HIF-1α antibody (sc-13515, 1:500 dilution), mouse monoclonal β-actin antibody (sc-8432, 1:2500 dilution), and rabbit polyclonal SCF antibody (sc-9132, 1:1000 dilution) were obtained from Santa Cruz Biotechnology. The secondary antibodies preparation was either anti-rabbit (1:5000) or anti-mouse (1:5000).
For cell functional experiments: rabbit polyclonal neutralizing SCF antibody (ab9716, 0.01 μg/mL) was obtained from Abcam.
