一般說明

曲古抑菌素A是一种一级羟肟酸。[1]

應用

曲古抑菌素A即用型溶液已用于:
  • 作为组蛋白去乙酰化酶抑制剂,通过干细胞试验研究其对转录组变化的影响[2]
  • 抑制原代垂体细胞培养物中的I、II或III类组蛋白去乙酰化酶(HDAC),用于研究内源性人生长激素基因(hGH)的胰岛素调节[3]
  • 处理细胞进行HDAC抑制实验[4]

生化/生理作用

曲古抑菌素 A (Trichostatin A,TSA) 是一种 链霉菌 代谢产物,在纳摩尔浓度下特异性抑制哺乳动物组蛋白去乙酰化酶,引起哺乳动物细胞内高度乙酰化的组蛋白分子积累。因此,曲古抑菌素 A 可用作研究体内组蛋白乙酰化的工具。曲古抑菌素 A 诱导细胞分化、细胞周期阻滞、逆转转化细胞形态和凋亡,并能够调节转录。TSA 已被用于建立一种新的克隆技术,从而提高了小鼠克隆的成功率。

Reversible acetylation at the epsilon-amino group of lysines located at the conserved domain of core histones is supposed to play an important role in the regulation of chromatin structure and its transcriptional activity. One promising strategy for analyzing the precise

Questions

  1. How long is this reagent good for when stored at -20? Do we need to avoid freeze-thaw cycles?

    1 answer
    1. This product may be stored at -20°C in aliquots at least until the recommended retest date published in the Certificate of Analysis. Avoid repeated freeze/thaw cycles.
