Cell growth Inhibition assay by free and conjugated drugs. Growth inhibiting effect of drug-conjugates VS free drugs was studied on a chlorambucil, b melphalan, c bendamustine. At the end of 72 h incubation period cell growth was assessed using the XTT assay: optical density (OD) was measured at 480 and 680 nm—the latter is the background absorbance. The difference between the 480 and 680 nm measurement was used to calculate the % growth inhibition (GI) in test wells compared with control cells exposed to medium alone. The results shown for each concentration point represent the mean ± standard error for two independent experiments each conducted in (n = 3)
