we studied the nature of the structures that keep ribosomes and polysomes immobilized within the cytoplasm of embryonic cells at cleavage through tailbud stages , using various combinations of a low-salt buffer ( 20 mm kcl ) , a high-salt buffer ( 500 mm kcl ) , 0.5 % doc , and 0.5 % triton x-100 .
