| 摘要 |
<p>The compositions of the present invention comprise one or more palladium bound ligands that are covalently bonded to inorganic or organic solid supports. These palladium bound ligands bonded to solid supports can be used for single heterocyclic amine base separation, or can be used to separate nucleotide chain containing specific sequences from other nucleotides or nucleotide chains. In one aspect of the invention, each ligand present is individually complexed to a single Pd(II)ion. If there are from 2 to 4 ligands present in the composition, then each ligand present must be separated from the other ligands by at least 3 atoms, preferably from 3 to 20 carbon atoms or equivalent spacing.</p> |
