I labeled my cells with pHrodo Red dextran dye to examine endocytosis of my adherent cells. After labeling with the recommended concentration in PBS, the cells rounded up and dissociated. Is this a problem with this reagent?
pHrodo Red dextran dye is not known to be toxic to cells. What is more likely is that the cells are not healthy in PBS in the amount of time needed for the assay. Instead, we recommend labeling in a more physiological buffer, such as HBSS, or in phenol red-free media, at an optimal temperature for your cells.
