Figure 2.
The disruption of proteoglycans does not inhibit motion, but does affect binding. (A) Distribution of PA-QD speeds following sodium chlorate treatment for the removal of sulfated proteoglycans, 37°C. The gray line shows the distribution for untreated cells. (B) PA-QD binding after washing of sodium chlorate-treated (NaClO3) and control cells. Scale bars: 10 μm. The same effect is seen for PEI-QDs.
