一般說明

丙酮酸激酶（PK）是催化糖酵解途径中最后一步的酶，能催化将磷酸基团从磷酸烯醇式丙酮酸（PEP）转移到ADP，生成一分子丙酮酸盐和一分子ATP。由于丙酮酸激酶表达或活性的缺陷会造成的丙酮酸激酶缺乏症，是溶血性贫血的第二大常见原因。

丙酮酸酶活性检测试剂盒提供了一种简单且直接的检测多种生物样品中丙酮酸激酶活性的方法。丙酮酸的浓度可通过偶联酶促反应来测定，此反应会生成与样品中的丙酮酸含量成正比的比色(570 nm)/ 荧光(λex = 535/λem = 587 nm)产物。一单位丙酮酸激酶的定义为，在25℃ 条件下每分钟将一个磷酸基团从PEP转移到ADP生成1μmol 丙酮酸所需的酶量。

應用

丙酮酸激酶活性测定试剂盒已用于测定样品中丙酮酸激酶的活性。

適合性

适用于测量各种生物样本中的丙酮酸激酶活性，如血液、组织和培养细胞等

原則

丙酮酸激酶活性测定试剂盒提供了一种简单直接的方法，来测量各种生物样品中的丙酮酸激酶活性。通过偶联酶测定法测定丙酮酸浓度，其产生与存在的丙酮酸盐成比例的比色（570nm）/荧光（λex = 535/λem = 587 nm）产物。一个单位的丙酮酸激酶是在 25℃ 下，每分钟将磷酸基团从 PEP 转移到 ADP，以产生 1.0 μmole 丙酮酸的酶量。

Whole-exome sequencing has been incredibly successful in identifying causal genetic variants and has revealed a number of novel genes associated with blood and other diseases. One limitation of this approach is that it overlooks mutations in noncoding regulatory elements. Furthermore

需氧糖酵解和瓦博格效应

本页面介绍了一篇有关瓦博格效应的文章，以及其如何能够在正常氧气水平下，增强肿瘤细胞中葡萄糖向乳酸的转化。Otto Heinrich Warburg在1924年证明，癌细胞显示出对糖酵解的依赖性增加，以满足他们的能量需求，无论是否有充足的氧气存在。
