    • The invention relates to enzymatic assays for assessing protein deacetylase activity of a protein deacetylase family, such as the histone deacetylase (HDAC) family or a sirtuin family. More particularly, the invention relates to such assays utilizing primary intact whole cells taken directly from the body of a mammal. Total protein deacetylase activity or isotype-specific activity is measured using assays which include a cell-permeable substrate that allows the production of a detectable reporter molecule in response to deacetylase activity. The effect of inhibitors and activators of the protein deacetylase family on protein deacetylase activity can also be measured.
    • 本发明涉及用于评估蛋白脱乙酰酶家族(例如组蛋白脱乙酰酶(HDAC)家族或沉默调节蛋白家族)的蛋白脱乙酰酶活性的酶测定法。 更具体地说,本发明涉及利用直接从哺乳动物体内取得的原代完整全细胞的此类测定。 使用测定法测定总蛋白脱乙酰酶活性或同种型特异性活性,所述测定法包括允许响应脱乙酰酶活性产生可检测报道分子的细胞可渗透底物。 也可以测量蛋白质脱乙酰酶家族的抑制剂和活化剂对蛋白质脱乙酰酶活性的影响。
