Abstract
Proteins isolated from ribosomal subunits of various mammalian cels were analysed comparatively by two different methods: a two-dimensional polyacrylamide gel electrophoresis system and a recently described two-dimensional immunoelectrophoresis technique. For this purpose, antisera were raised in rabbits against the total mixture of ribosomal proteins from murine cells. These sera were characterized by ring-test, double immunodiffusion and two-dimensional immunoelectrophoresis. They were shown to contain antibodies to a large number of ribosomal proteins. Immunoelectrophoretic analysis of 60S and 40S subunit proteins from rabbit, lamb, canine and human cells using anti-murine sera revealed a striking conservation of their antigenic properties. These results corroborated those obtained by two-dimensional polyacrylamide gel electrophoresis.
