Fig. 7From: Tracking dipeptides at work-uptake and intracellular fate in CHO cultureCHO culture supplemented with l-alanyl-l-tyrosine (AY). Time courses of the dipeptide and of the related amino acids are monitored in the culture medium (a) and in intracellular extracts (b). Open circles represent concentrations found in the control culture which did not have AY supplementation. Error bars describe the standard deviation of three analytical replicates.
