Uptake and photodynamic efficiency of hematoporphyrin, hydroxyethylvinyldeuteroporphyrin and hematoporphyrin derivative (Photofrin II): a study with isolated mitochondria.

The uptake of Photofrin II (PFII), hematoporphyrin (Hp) and hydroxyethylvinyldeuteroporphyrin (HVD) by isolated mitochondria was studied using the high performance liquid chromatography (HPLC) technique. The various PFII components show a high affinity for mitochondria. At 5.75 micrograms/ml PFII, their ratio of incorporation was found to be very similar… (More)
