Materials and MethodsPreparation of Rod Disk Membranes. Dark-adapted and frozen bovine retinas were purchased from George A. Hormel Co.(Austin, MN) and stored at-40 C until use. Preparative procedures were carried out at 0-4 C under infrared illu-mination with the aid of imageconverters. All centrifugations utilized an SS 34 rotorin a refrigerated Sorval centrifuge. Frozen retinas were thawed in 1 mL per retina of 45% w/v sucrose in MOPS buffer [20 mM 4-morpholinepropanesulfonic acid (MOPS), 100 mM KC1, 2 mM MgCl2, 1 mM dithiothreitol (DTT), and 0.1 mM ethylenediaminetetraacetic acid (EDTA), pH 8.0] and vortexed at maximum speed for 60 s. The suspension was diluted in the same medium to about 2.5 mL per retina, overlaid with 2 mL of MOPS buffer, and spun at 15 000 rpmfor 30 min. The carpet of rod outer segments at the interface was collected, diluted into 2 volumes of buffer, and spun at 15 000 rpm for 15 min. The pellet was resus-pended in buffered sucrose, floated on sucrose, and washed again. The final pellet was suspended in a small volume of
