Fig 4. Dual -CE/protein-labeled LDL uptake and sorting.

HeLa cells were plated at 30% confluency on glass covered slips and then pre-incubated in serum free media for 24 hours prior to experiments. CE/protein-labeled LDL were added to the media for 1 hour, washed and chased for 30–60 minutes in serum/lipoprotein free media. The data is arranged in rows with a color code seen on the right side of the panels. The bar corresponds to 10 μm, *p < 0.015, **p<0.01.
