[Antigenicity of ribosomal proteins from a malignant mouse cell line. Preliminary results].

An original immunological two-dimensional technique with two different gels permits the protein analysis of 80 S cytoplasmic ribosomal murine particles and of their 60 S and 40 S subunits. The diagrams isolate and characterize a definite number of specific polypeptidic structures from each ribosomal particle.
