The final major set of DBPs have structural problems that are also quite challenging because they involve characterization of RNA:protein complexes. The RNA samples often need to be folded in relatively high concentrations of Mg2+ which can complicate the spectra by adducting to the samples. In addition, the RNA preparation procedures often lead to heterogenous populations of RNA with different lengths, splitting the signal over multiple peaks. The Wysocki group has obtained extensive experience in the native MS characterization of RNA:protein complexes because of the strong Center for RNA Biology at OSU. By continuing to build our expertise on these types of samples, nucleoprotein investigations nationally and internationally will be provided with useful protocols for characterization of stoichiometry, connectivity, and CCS of RNA protein complexes.
