    • A process for protecting a short RNA fragment includes labeling a short RNA fragment with a detectable platinum compound forming a labeled small RNA fragment. Resulting labeled short RNA fragment is exposed to a capture oligonucleotide. The capture oligonucleotide includes at least two replicates of a nucleotide sequence complimentary to the short RNA fragment nucleotide sequence. The labeled short RNA fragment and the captured oligonucleotide sequence are brought into contact under hybridization conditions. With hybridization, the marker moiety is detected on the hybridized labeled small RNA fragment-captured oligonucleotide conjugant. A detection array for short RNA fragment includes a substrate having multiple spots, with a first spot including a first capture oligonucleotide including at least two replicates of a nucleotide sequence complimentary to a first short RNA fragment along with an additional nucleotide sequence functioning as a universal controller or spacer. Another spot on the array includes a second capture oligonucleotide having at least two replicates of a sequence complimentary to a second short RNA fragment along with an additional sequence functioning as a universal controller or spacer. Verified small RNA fragments are also obtained after mobilizing a sequence through elution and optional platinum compound removal therefrom.
    • 用于保护短RNA片段的方法包括用形成标记的小RNA片段的可检测铂化合物标记短RNA片段。 得到的标记的短RNA片段暴露于捕获寡核苷酸。 捕获寡核苷酸包括与短RNA片段核苷酸序列互补的核苷酸序列的至少两个重复。 标记的短RNA片段和捕获的寡核苷酸序列在杂交条件下接触。 通过杂交,在杂交标记的小RNA片段捕获的寡核苷酸共轭体上检测标记部分。 用于短RNA片段的检测阵列包括具有多个点的底物,第一个斑点包含第一个捕获寡核苷酸,其包含与第一个短RNA片段互补的核苷酸序列的至少两个重复以及用作通用控制器的另外的核苷酸序列 或间隔物。 该阵列上的另一个点包括具有与第二短RNA片段互补的序列的至少两个重复的第二捕获寡核苷酸以及用作通用控制器或间隔物的附加序列。 在通过洗脱动员序列和从其中除去任选的铂化合物后,也可以获得验证的小RNA片段。
