  Non-polar polymeric separation media, such as beads or monoliths, are suitable for chromatographic separation of mixtures of polynucleotides when the surfaces of the media are unsubstituted or substituted with a hydrocarbon group having from one to 1,000,000 carbons and when the surfaces are substantially free from mutivalent cation contamination. The polymeric media provide efficient separation of polynucleotides using Matched Ion Polynucleotide Chromatography. Methods for maintaining and storing the polymeric media include treatment with multivalent cation binding agents.

  非极性聚合物分离介质（如珠子或单片）适用于多核苷酸混合物的色谱分离，前提是介质表面未被取代或被具有 1 至 1,000,000 个碳原子的烃基取代，且表面基本不受二价阳离子污染。聚合介质可使用匹配离子多核苷酸色谱法有效分离多核苷酸。维护和储存聚合介质的方法包括使用多价阳离子结合剂进行处理。

  A Matched Ion Polynucleotide Chromatography method and system for size-based segregation of a mixture of RNA molecules. The method includes applying the mixture to a polymeric separation medium having non-polar surfaces and eluting the RNA molecules with a mobile phase which includes counterion reagent and an organic component. The preferred surfaces are characterized by being substantially free from multivalent cations which are free to interfere with RNA segregation. The elution is preferably performed at a temperature sufficient to denature the RNA. The method can be used in segregating RNA molecules having lengths in the range of about 100 to 20,000 nucleotides. Improved segregation is obtained using a chromatography column having an ID greater than about 5 mm. Examples of separation media include beads and monolithic columns.

  一种匹配离子多核苷酸色谱法和系统，用于根据大小分离 RNA 分子混合物。该方法包括将混合物应用于具有非极性表面的聚合物分离介质，并用包括反离子试剂和有机成分的流动相洗脱 RNA 分子。优选表面的特点是基本上不含干扰 RNA 分离的多价阳离子。洗脱最好在足以使 RNA 变性的温度下进行。该方法可用于分离长度在 100 至 20,000 个核苷酸范围内的 RNA 分子。使用内径大于 5 毫米的色谱柱可提高分离效果。分离介质的例子包括珠子和整体柱。

  The instant invention provides a method for stabilizing an RNA molecule against degradation comprising applying a solution to a separation medium having a non-polar separation surface in the presence of a counterion agent, wherein the solution comprises the RNA molecule and an agent capable of catalyzing the degradation of RNA; eluting the RNA molecule from the separation medium by passing through the separation medium a mobile phase containing a concentration of organic solvent sufficient to elute the RNA molecule from the separation medium, where the elution is conducted under conditions that result in a substantial separation of the RNA molecule from the agent capable of catalyzing the degradation of RNA; and collecting an eluant fraction containing the RNA molecule that is substantially free of the agent capable of catalyzing the degradation of RNA. In a preferred embodiment the method is performed under conditions that are substantially free of multivalent cations.
