一般描述
组蛋白脱乙酰化酶（HDAC）是从组蛋白中去除乙酰基的一大类酶。 已显示位点特异性组蛋白乙酰化和脱乙酰化分别激活或抑制真核基因转录，因此，它在哺乳动物发育和疾病中起关键作用。HDACs参与重要的生物学活动，例如细胞分化，增殖，凋亡和衰老。
使用Sigma′s HDAC3活性测定试剂盒，试样中存在的HDAC3将与提供的显影剂一起作用，使其脱乙酰化，然后裂解HDAC3底物[R-H-K-K（Ac）-AFC]。 该活性将释放淬灭的荧光基团AFC，可以在Em/Ex=380/500 nm处检测到。 曲古抑菌素A是试剂盒中包含的HDAC抑制剂，用于验证HDAC3活性。该试剂盒提供了快速，简单，灵敏和可靠的测试。 它适用于来自核提取物，纯化或免疫沉淀的HDAC3以及天然，重组或基因修饰的HDAC3的单独测试或高通量测定。

Alzheimer's disease (AD) is the leading cause of age-related dementia. Neuropathological hallmarks of AD include brain deposition of β-amyloid (Aβ) plaques and accumulation of both hyperphosphorylated and acetylated tau.
