Inhibition of [3H] PK11195 binding to V79 cell homogenates and live cells (Photofrin only) by photosensitive dyes. Binding studies performed as described in Materials and Methods demonstrate the selective interaction of the porphyrin phototoxic dye, Photofrin II, with MBR in homogenized and live V79 cells. Key for symbols: rhodamine 6G (open circles), rhodamine 123 (filled circles), merocyanine (open triangles), Photofrin II with V79 homogenates (filled squares), Photofrin II with live V79 cells (open squares).
