The conditions under which the highest activity in rabbit reticulocyte
lysates can be achieved have been studied by different investigators
(1,2). Hemoglobin represents about 90% of the total protein in rabbit
reticulocyte lysate. The effect of the absence of hemoglobin deserves
thus clarification. The present study shows that the activity of prote
in synthesis in hemoglobin-free rabbit reticulocyte lysate is higher t
han that of the control lysate.
