HIV-1 Reverse Transcriptase-Based Assay to Determine Cellular dNTP Concentrations
Deoxynucleoside triphosphates (dNTPs) are the building blocks of DNA and their biosynthesis is tightly regulated in the cell. HPLC-MS and enzyme-based methods are currently employed to determine dNTP concentrations from cellular extracts. Here, we describe a highly efficient, HIV-1 reverse transcriptase (RT)-based assay to quantitate dNTP concentrations. The assay is based on the ability of HIV-1 RT to function at very low dNTP concentrations, thus providing for the high sensitivity of detection.
