Proteins of the large ribosomal subunit of rat liver (TP 60) were immobilized by diffusion transfer onto nitrocellulose after two-dimensional polyacrylamide gel electrophoresis (2-D PAGE). Incubation of the TP 60 blots with 32P-labeled 5 S RNA under defined ionic conditions (300 mM KCl, 20 mM MgCl2) resulted in specific binding to a limited set of ribosomal proteins consisting of proteins L3, L4, L6, L13/15 and--to a lesser extent--L7 and L19. Under identical conditions, blots with proteins of the small ribosomal subunit (TP 40) did not bind 5 S RNA.
