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.
本发明的组成物包括一个或多个与无机或有机固体支撑物共价键结合的钯结合配体。这些与固体支撑物结合的钯结合配体可用于单一杂环胺基分离,或可用于从其他核苷酸或核苷酸链中分离包含特定序列的核苷酸链。在本发明的一个方面,每个存在的配体都单独与单个Pd(II)离子形成配合物。如果组成物中存在2到4个配体,则每个存在的配体必须至少与其他配体相隔3个原子,最好是从3到20个碳原子或等效间隔。
