title: Translation of endogenous message in embryonic chick erythroid cell polysomes in a cell-free protein-synthesizing system.
abstract: Polysomes from 5.5-day and 6.5-day embryonic chick erythroid cells contain messenger RNA (mRNA) which can be translated into products in a cell-free protein-synthesizing system. The products of the cell-free system coelectrophoresed with carrier globin chains from the cells from which the polysomal pellet was isolated. Wheat germ S30 fraction increases by 1.5--2.0 fold [3H] leucine incorporation into trichloroacetic acid-precipitable material directed by the endogenous mRNA on chick erythroid cell polysomes. The wheat germ probably provides a specific factor or factors absent in a shortage in the incubation medium.
