Uptake of fluorescence tagged AF-SWCNTs by PMs and PLE cells.

<p>Peritoneal macrophages and PLE cells were cultured in 48 well plates in presence of fluorescent tagged AF-SWCNTs (5 µg/ml). At different time periods, cells were washed with PBS and harvested by trypsinization. Percentage of cells positive for AF-SWCNTs was determined by using a flow cytometer. Each point represents Mean ±SEM of values obtained from 3 replicate assays.
