A method for isolating RNA from RNA containing samples wherein the RNA containing sample is treated with at least one DNase and/or another enzyme like proteases or collagenases for purification of RNA in presence of a complex of ribonucleosides and the oxovanadyl ion which is capable of inhibiting RNases present in the RNA containing samples and removing the complex of ribonucleosides and the oxovanadyl ion prior to down-stream processing of the RNA of the RNA containing sample by contacting the sample of the forgoing step with a chelating agent immobilized to a support, the chelating agent having sufficient affinity to the complex of ribonucleosides and the oxovanadyl ion so that it binds to the chemical entity and the RNA containing sample is freed from the inhibitor.
一种从含 RNA 样品中分离 RNA 的方法,其中用至少一种 DNase 和/或另一种酶(如
蛋白酶或
胶原酶)处理含 RNA 样品,以便在
核糖核苷和氧
钒离子复合物存在的情况下纯化 RNA,该复合物能够抑制含 RNA 样品中存在的 RN 酶,并在下游处理含 RNA 样品的 RNA 之前除去
核糖核苷和氧
钒离子复合物。在对含 RNA 样品的 RNA 进行下游处理之前,将前述步骤中的样品与固定在支持物上的
螯合剂接触、
螯合剂对
核糖核苷和氧杂
环戊烯离子的复合物有足够的亲和力,从而与
化学实体结合,使含有 RNA 的样品脱离
抑制剂。
