free polyribosomal poly ( a ) -containing rna isolated from normal rat liver was used to prepare a complementary dna plasmid library in the pst1 site of the plasmid pat153 . a plasmid pgstr155 complementary to mrna coding for a glutathione transferase ya subunit was selected by differential hybridization in situ and preliminary characterization was performed by hybrid-selected mrna translation , immunoprecipitation and polyacrylamide-gel electrophoresis of the product synthesized in vitro .
