Analysis of membrane permeability, cell morphology and antigen expression in TransFix<sup>®</sup> treated cells.

<p><b>A.</b> Staining with 7-AAD reagent at different times after treatment and comparison with equivalent fresh cells. <b>B.</b> Forward (FSC) and side scatter (SSC) parameters were acquired at several time points (shown for 120 days), and compared with fresh cells. <b>C.</b> Antigen expression levels of MELDia cells (HIRO.71 staining) or CHOLua cells (BRIC221 staining) at 120 days of treatment (fresh cells are overlaid); negative controls were MELwt or CHOwt cells stained in matching conditions.</p>
