Figure 2From: Quantum dot imaging for embryonic stem cellsQtracker intracellular QD delivery quantified by flow cytometry. (A) Flow cytometry detection of QD labeling of mouse ES cells on day 1, day 4, and day 7. Red line = unlabeled cells as control; green line = cells labeled with QD. (B) Fluorescent images of cells labeled with QDs on day 1 post labeling.Back to article page
