Biodistribution quantification of fixed tissue samples by 19F NMR at 2 days and 7 days post treatment. 19F NMR measurements of organ biodistribution of the PFC-labeled CAR-T cells and untransduced T cells show strong liver, lungs, lymph node, and tail signal but modest signal in the spleen and tumors in both groups. Data is presented as the average fluorine atom content per organ (top) and the corresponding apparent cell number (bottom). These measurements do not account for cell division, thus referred to as “apparent cell number”. The tail signal represents mis-injection
