Fig 9. Ecto-5′-nucleotidase activity in HUVECs.

HUVECs were treated without (control) or with abacavir (10 μM) for 24 h and the activity of ecto-5’ nucleotidase measured. Values are means ± S.E.M. of three sets of experiments carried out in triplicate and statistical comparisons were made using Student’s t-test.
