Amino Acid availability in expanded CAR T cells. Amino acid content deduced from 1H NMR spectra of supernatant samples from CAR T cells before feeding, compared with fresh medium samples taken on the same day. N = 3 biological CAR T cell replicates from the same donor expanded independently. The amino acids are shown in the following order: (A) Arginine (Arg), (B) Cysteine (Cys), (C) Histidine (His), (D) Isoleucine (Ile), (E) Leucine (Leu), (F) Phenylalanine (Phe), (G) Tyrosine (Tyr), (H) Valine (Val).
