Autoradiographic image of plasma samples. Autoradiography image of plasma samples obtained from a rat injected with [18F]FAZA (left) and from a pig injected with [18F]FEPPA (right). “Ref” is the reference spot on each TLC plate. The number above each line shows the time in min at which the blood sample was drawn post tracer injection. The direction of motion of the mobile phase (solvent) front from capillary action was from bottom to top. The radio-metabolites that did not move with mobile phase show up as faint “spots” at the bottom along the spotting line
