Figure 2. AZA incorporates into RNA and DNA of KG-1a cells.

KG-1a cells were treated with 0.3 µM radiolabeled AZA ([¹⁴C]-AZA) for 24 hours. The amount of AZA incorporated into total nucleic acid, DNA, and RNA was quantified as described previously. Standard error of the mean was determined from 3 independent experiments, including triplicate wells per experiment. AZA  =  azacitidine.
