Oscillations in erythrocyte membrane preparations.
The ratio of weakly and strongly immobilized populations of membrane-bound maleimide spin label, the excimer to monomer fluorescence ratio of membrane-embedded pyrene, and acetylcholinesterase activity, were evaluated in bovine erythrocyte membrane preparations incubated at 37 degrees C. Oscillations were evident in the values obtained, and the periods of these oscillations were in the range of 1.3 to 1.6 h.
