Sampleprep Summary: | CAR-T cells were isolated as described above either from in vitro culture or from bone marrow harvested in an in vivo study. The cells were washed in PBS and frozen at -80C until the assay is ready to run. Metabolites from cells were extracted at 2x106 cells/ml at 4°C (30 min) in the presence of 5:3:2 MeOH:MeCN:water (v/v/v). The samples were spun down and the resulting supernatant was transferred to new tubes and dried under a vacuum. The resulting residue was reconstituted in 0.1% formic acid at a 3x concentration, then analyzed on a Thermo Vanquish UHPLC coupled to a Thermo Q Exactive MS as previously described in detail. |
