摘要： The invention provides enzymatic methods for direct determination of percentage of glycated hemoglobin in blood samples without the need of a separated measurement of total hemoglobin content in blood samples. The methods utilizes one or two different types of oxidizing agents which selectively oxidize low-molecular weight reducing substances and high-molecular weight (mainly hemoglobin) reducing substances in blood samples, coupled with enzymatic reactions catalyzed by proteases, fructosyl amino acid oxidase, and peroxidase. The invention provides kits for performing the methods of the invention.

摘要： This invention relates generally to the field of homocysteine detection. In particular, the invention provides a method for determining homocysteine presence or concentration in samples, which method comprises: contacting a sample containing or suspected of containing Hcy with a Hcy co-substrate and a Hcy converting enzyme in a Hcy conversion reaction to form a Hcy conversion product and a Hcy co-substrate conversion product; and assessing the Hcy co-substrate conversion product to determine the presence, absence and/or amount of the Hcy in the sample. The Hcy co-substrate conversion product may be assessed directly, or it may be assessed by further conversion of the Hcy co-substrate conversion product into another material by the action of one or more additional enzymes. A kit for assaying homocysteine based on the same principle is also provided.
摘要翻译：本发明一般涉及同型半胱氨酸检测领域。特别地，本发明提供了一种测定样品中同型半胱氨酸存在或浓度的方法，该方法包括：在Hcy转化反应中使包含或怀疑含有Hcy的样品与Hcy共底物和Hcy转化酶接触以形成Hcy 转化产物和Hcy共底物转化产物; 并评估Hcy共底物转化产物以确定样品中Hcy的存在，不存在和/或量。可以直接评估Hcy共底物转化产物，或者可以通过一种或多种另外的酶的作用将Hcy共底物转化产物进一步转化成另一种物质来评估。还提供了用于基于相同原理测定同型半胱氨酸的试剂盒。
