simultaneous labeling of newly synthetized proteins with [ 3h ] fucose and [ 14c ] valine showed a 3-fold higher ratio of [ 3h ] fucose to [ 14c ] valine in the released protein fraction compared to the soluble cytoplasmic protein and to the crude membrane protein fraction , suggesting that the soluble released proteins are more highly glycosylated than the proteins retained in the tissue .
