Distribution of radioactivity in tumours derived from 18F-FMISO injected mice.
(A) Distribution of radioactivity from 18F-FMISO between a fraction covalently bound to macromolecules and a low-molecular-weight fraction. Data are means ± s.d. (n = 3). (B) Radio-HPLC chromatogram of the low-molecular-weight fraction of FMISO. (C,D) Autoradiograph (ARG) of tissue sections without (C) and with (D) washing. Scale bar represents 1 mm. (E) Immunohistochemical staining for pimonidazole. Scale bar represents 1 mm.
