the following experimental strategy was pursued : in order to elucidate binding of a protein to 23s rna or a protein-protein interdependence , 23s rrna and a set of purified ribosomal proteins were incubated under reconstitution conditions , the rna-protein complex was separated from the non-bound proteins by sucrose gradient centrifugation and the proteins contained in the complex were determined by means of gel electrophoresis .
