  • Ribonucleoside Vanadyl Complex


    Ribonucleoside-vanadyl complex is a potent inhibitor of various ribonucleases (1,2,3). This complex is compatible with cell fractionation methods as well as sucrose-gradient centrifugations. The 200 mM stock solution is reconstituted to a green-black clear solution by incubating the sealed vial at 65°C. Once open, the entire sample should be aliquoted into smaller samples and frozen.

    The ribonucleoside-vanadyl complex should be added to all buffers to a final concentration of 10 mM. The buffers should not contain EDTA since one equivalent will totally dissociate the complex.

    We do not recommend the use of the vanadyl complex in cell-free translation systems and with reverse transcriptase (5). The vanadyl complex can be used in the selective degradation of DNA while preserving RNA since pancreatic deoxyribonuclease I is not inhibited (5). Removal of the ribonucleoside-vanadyl complex from the RNA can be accomplished by adding 10 equivalents of EDTA before ethanol precipitation.

    Product Source

    This vanadyl complex is prepared from a modification of procedures by Lienhard using all four ribonucleosides (4).
