Low dose sulf1 MO injection (15 <i>μ</i>M) in the yolk sac of 1-2 cell stage zebrafish with the respective DMSO control in the surrounding medium did not induce a significant reduction of the maximum fluorescence intensity compared to a scrambled control (CTRL) with DMSO control. The addition of 2 or 8 mg/ml of PAN in the surrounding medium however induced a reduction of the maximum fluorescence indicating additional fusion protein loss.</p>
