Fig. 4From: Simultaneous and absolute quantification of nucleoside triphosphates using liquid chromatography–triple quadrupole tandem mass spectrometryPossible mechanism of change in dNTP levels in Molm-13 cells induced by 2000 μM thymidine treatment for 24 h. RNR, ribonucleotide reductase; dT, thymidine. The width of the arrows indicating “increase” reflects the amount of change in the dNTP induced by thymidine treatmentBack to article page
