一般說明
HMG-CoA 还原酶测定试剂盒是胆固醇和其它相关代谢途径基础研究的重要工具。
應用
HMGR活性试剂盒可用于测定HMG-CoA还原酶活性。该试剂盒的主要功能是筛选HMG-CoA还原酶的纯化后催化亚基的不同抑制因子和激活因子，这在临床治疗中具有重要意义。该检测方法针对340nm处的吸光度下降进行光谱测量，而后者恰恰反映了存在HMG-CoA底物时HMGR催化亚基对NADPH的氧化水平。
生化／生理作用
HMGR（3-羟基-3-甲基戊二酰-CoA还原酶）是位于内质网上的一种跨膜糖蛋白。 这种酶可以催化HMG-CoA的四电子还原反应，生成辅酶A（CoA）和甲羟戊酸。这是固醇生物合成中的限速步骤。 为了维持衍生的甲基戊酸酯的浓度，可以通过合成、降解、磷酸化等方式控制HMGR的活性。除了HMGR的生理调控之外，人的HMGR酶可成功通过药物来靶定调控，可用于高血清胆固醇的临床治疗。 控制血清胆固醇体水平具有非常重要的治疗作用，这是因为血胆脂醇过多往往会引起动脉硬化病症加剧，进而引起心血管疾病，这可能会引起冠心病和中风。目前已有证据表明，胆固醇体内平衡受到干扰会引起慢性炎症恶化。
