    • An improved, highly stable capillary column used in high performance capillary electrophoresis and method of preparing the same. The improved capillary column can significantly reduce the effects of electroosmosis during electrophoresis, is stable for reuse, and enables operation of the capillary column in high electric fields, resulting in high resolution separations in a minimum amount of time. The improved column comprises a capillary having a highly stable, coating matrix on the inner surface of the capillary wall. The highly stable coating matrix includes an intermediate layer hydrophobic phase chemically bonded to the inner wall of the capillary, a detergent which is physically adsorbed to the hydrophobic phase, and a polymerized monomer which is covalently bonded to the adsorbed detergent thereby forming a hydrophilic outer layer of the coating matrix.

    • Analytical methodology is disclosed in which a trace analyte in a sample is tagged to increase its signal strength for measurement, and an affinity substance is used at least after the tagging step (late in the method) to separate the tagged analyte from tagging noise, wherein the affinity substance is directed at the reactive part of the tag, at the reagent-reacted part of the tag, or at a nonreactive part of the analyte. This method includes the case where exposure of the sample to the affinity substance begins prior to and continues after the tagging reaction. The affinity substance comprises an affinity reagent such as an immobilized anti-body (immuno-affinity chromatography). This late use of an affinity substance (after the tagging reaction) is particularly important for methods in which trace analytes are reacted with a charge tag (tag possessing a charge) prior to detection by mass spectrometry.
    • 公开了分析方法,其中样品中的痕量分析物被标记以增加其用于测量的信号强度,并且至少在标记步骤(方法后期)使用亲和物质以将标记的分析物与标记噪声分离,其中 亲和性物质指向标签的反应性部分,标签的试剂反应部分或分析物的非反应性部分。 该方法包括样品暴露于亲和性物质之前开始标签反应之前和之后的情况。 亲和性物质包括亲和试剂如固定化抗体(免疫亲和层析)。 亲和性物质的后期使用(标记反应后)对于通过质谱法检测之前将痕量分析物与电荷标签(具有电荷的标签)反应的方法特别重要。

    • A method for amplifying enzyme activity is disclosed. Enzyme amplification is achieved by covalently bonding enzyme to a supporting material via a molecular chain which is a substrate for the enzyme, then introducing a small amount of enzyme in the free state to this system, causing release of a large amount of bound enzyme. In an alternative embodiment, complementary enzymatically inactive fragments of an active enzyme, which fragments can recombine to form active enzyme, are covalently attached to separate support materials by a molecular chain material which is a substrate for the active enzyme, and these two fragment-supported conjugates are connected in series. Upon application of free enzyme or free complementary enzyme to one of these fragment-support conjugates, followed by application of the resulting product mixture to the second fragment-support conjugate, a large amount of free enzyme is ultimately produced. In a second alternative embodiment, two different active enzymes are each attached to separate supporting materials by different leashes, in which the leash for the first enzyme only is cleaved in the system by the second enzyme, and the leash for the second enzyme only is cleaved in the system by the first enzyme. These two materials are connected in series, and upon application of the second enzyme to the first enzyme-support conjugate, followed by application of the released first enzyme to the second enzyme-support conjugate material, ultimately a large amount of released active second enzyme is produced. Also disclosed are molecular conjugates of enzyme material on supports, required for the enzyme amplification.
    • 公开了扩增酶活性的方法。 酶扩增是通过将作为酶的底物的分子链共价键合到支持材料上,然后将少量酶以自由状态引入该系统,引起大量结合的酶的释放。 在替代实施方案中,活性酶的互补的酶促无活性的片段可以重组以形成活性酶,通过作为活性酶底物的分子链材料共价连接到分离的载体材料上,并且这两个片段支持 缀合物串联连接。 当将游离酶或游离的互补酶应用于这些片段 - 支持的缀合物之一时,随后将所得的产物混合物施用到第二片段 - 支持缀合物上,最终产生大量的游离酶。 在第二替代实施方案中,两种不同的活性酶各自通过不同的皮带连接到分离的支持材料,其中第一酶的皮带仅在系统中被第二酶切割,并且第二酶的皮带仅被切割 在系统中由第一种酶。 这两种材料是串联连接的,并且在将第二种酶施用于第一种酶 - 载体缀合物后,随后将释放的第一种酶施用于第二种酶 - 载体缀合物材料,最终大量释放的活性第二种酶是 生产。 还公开了在酶扩增所需的载体上的酶材料的分子缀合物。
