Immunochimie des polyribonucléotides: I. Homopolymères à une ou plusieurs chaînes

摘要: Abstract Immunochemistry of polyribonucleotides. I. Single or multiple chain homopolymers Anti-RNA antibodies NG 1 were prepared in solutions containing no electrolytes. Precipitation reactions the polyribonucleotides performed media very low ionic strength saline varying concentrations. At zero strength, all precipitated equally, which shows that nature base does not determine, neither qualitatively nor quantitatively, precipitation reaction. When concentration electrolytes was increased, immunochemical behaviour varied according level organization used. In case poly (U), it seen characteristics are linked to its randomly coiled conformation. On other hand, modifications (A) (C) at neutral pH attributed intramolecular organization. Finally, this method analysis allowed us show (I) solution takes on a variable number strands, depending and
