Changes in turbidity of the media (DMEM plus 10% FBS; dark bars) expressed as Nephelometric Turbidity Units (NTU) in the absence (control, C) and presence of ALP substrate β-glycerophosphate (5 mM; B) and ALP inhibitor levamisole (1 mM; L) after 14 days of incubation. Turbidity of paired samples of DMEM without FBS (light bars) was near background. Statistically significant difference. (P < 0.05) from: *, 10% FBS control; †, corresponding 10% FBS sample.
