Mass spectrometry is a powerful tool for studying the intracellular pharmacokinetics of antiretroviral drugs. However, the biohazard of HIV-1 calls for a safety protocol for such analyses. To this end, we extracted HIV-1 producing cells with methanol or ethanol at 4 °C. After extraction, no viral infectivity was detected, as shown by a reduction in infectious titers of more than 6 log. In addition, this protocol is compatible with the quantitative analysis of antiretroviral drugs in cell extracts using matrix-assisted laser desorption/ionization time-of-flight (MALDI-TOF) MS. Thus, using this protocol, infectious HIV-1 is inactivated and antiretroviral drugs are extracted from cells in a single step.
