  Provided herein are novel irreversible sialidase inhibitors. These compounds can be conjugated with a detectable tagging moiety such as azide-annexed biotin via CuAAC for isolation and identification of sialidases. The provided compounds and the corresponding detectable conjugates are useful for detecting sialidase-containing pathogens and imaging in situ sialidase activities under physiological conditions.

  The present invention provides systems and methods for production of activatable diazo-derivatives for use in labeling nucleotides. Labeling nucleotides is accomplished by contacting a stable hydrazide derivative of a detectable moiety with an activating polymer reagent which is used to directly label the nucleotide sample. Labeling occurs on the phosphate backbone of the nucleotide which does not perturb hybridization of the labeled nucleotide with its anti-sense strand. Since the method involves direct labeling, all types of nucleotides can be labeled without prior amplification or alteration.

  本发明提供了用于生产可激活重氮衍生物以用于标记核苷酸的系统和方法。通过将可检测基团的稳定的肼酰肼衍生物与用于直接标记核苷酸样品的活化聚合物试剂接触来完成核苷酸的标记。标记发生在核苷酸的磷酸骨架上，不会干扰标记核苷酸与其反义链的杂交。由于该方法涉及直接标记，所有类型的核苷酸都可以在不经过扩增或改变的情况下进行标记。

  Cleavable nucleotide analogs are provided. The nucleotide analog includes a nucleotide molecule attached to a cleavable moiety wherein the cleavable moiety comprises a protective group and/or a linker attached to a fluorophore. The cleavable moiety is linked to the oxygen atom of the 3'-OH of the pentose of the nucleotide molecule. The nucleotide analogs can be used in making polynucleotide molecules using template independent polymerases. The nucleotide analogs can act as reversible terminators during DNA sequencing by synthesis. The cleavage of the cleavable moiety restores a free 3'-OH functional group allowing growth of the polynucleotide molecule. The general structures as well as proposed synthetic schemes for the nucleotide analogs are also provided.

  可切割的核苷酸类似物已提供。该核苷酸类似物包括连接到可切割基团的核苷酸分子，其中可切割基团包括保护基团和/或连接到荧光团的连接物。可切割基团连接到核苷酸分子的五碳糖的3'-OH的氧原子。这些核苷酸类似物可用于使用模板无关聚合酶制备多核苷酸分子。这些核苷酸类似物在DNA合成测序过程中可作为可逆终止子。切割可切割基团恢复自由的3'-OH官能团，从而促进多核苷酸分子的生长。还提供了核苷酸类似物的一般结构以及拟议的合成方案。
