微观研究

Since I joined the institute, my efforts have been mainly contributed to set up the RNA platform with the large-scale zonal gradient ultracentrifuge isolation system and reverse-phase HPLC system. At the meantime, I set up the in vitro translation system as the working method to study the ribosome and the translational factor LepA(EF4) functionally and structurally.

The above method can be used as a general method of determining molecular weight distribution of polymers.4.Solid-state ~1H wide-line NMR and ~(31)p magic angle spinningNMR were applied to a series of PEI/DNA complex samples with different PEI molecular weights and nitrogen/phosphatemolar ratios,in order to disclose the influence of various structural factors on the interactions and morphology.The results of ~1H NMR spectra showed that the linewidth of the PEI signal was greatly broadened with increasing the N/P ratio.Meanwhile,in the ~(31)p M_AS experiment,the signal was found to shift upfield with the increase of the N/P ratio.Both ~1H and ~(31)P NMR experiments demonstrated that the interaction between two constituents and subsequently the morphology of the complexes vary with the N/P ratio.
