2 Figure 1 Cell survival of SW480 line for different concentrations of ALA: 0μM, 500μM, 1000μM and 1500μM and different light fluences: 0J/cm2, 10J/cm2, 30J/cm2 and 60J/cm2 in the absence of cobalt(II) chloride (CoCl2) (normoxia conditions) in environment determined by MTT assay as percentage of survival of control group. The values represent the mean±SD of four independent experiments (n=16). Photodiagnosis and Photodynamic Therapy  , 27-35DOI: ( /j.pdpdt ) Copyright © 2015 Elsevier B.V. Terms and Conditions
