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.
