Fig. 1From: Mass spectrometry imaging of L-[ring-13C6]-labeled phenylalanine and tyrosine kinetics in non-small cell lung carcinomaEleven mice were injected with ring-13C6-Phe and three additional mice were injected with normal saline into the lateral tail vein when the tumors reached 1000 mm3. The tracer-infused mice were subsequently sacrificed at 10 min (n = 4), 30 min (n = 3), and 60 min (n = 4) after injection, and sham-treated mice were sacrificed after 10 minBack to article page
