Figure 6.
MS analysis of single HEK 293T cells that have undergone apoptosis after being treated with 35 mM ethanol for 20 min. Representative phase-contrast images of (A) an untreated cell and (B) an apoptosis-induced cell with a yellow line to denote where the scanning was performed; (C, D) Relative amounts of total ion current acquired from a LDIDD-MS scan of the untreated and apoptosis-induced cells, respectively; (E, F) Mass spectra of the untreated and apoptosis-induced cells, respectively. The scale bar shown in (A–D) is 10 μm.
