attempts to separate dissociated ribosomal protein and the remaining core particles treated with 1.25 m kcl by centrifugation of the salt-treated particles though a 40 % sucrose cushion led to the observation that ribosomal subparticles isolated in this manner retained full phenylalanine incorporating activity , whereas centrifugation through other solutions resulted in inactive or less active particles .
