应用

从鲑鱼精子中提取的不同浓度的低分子量脱氧核糖核酸已用于：
  • 研究DNA与硅取代羟基磷灰石纳米晶体的结合。
  • 在简单的电化学DNA生物传感器中检测和评估UV-C辐射和活性氧造成的DNA损伤。
  • 作为合成生物点的前体。

生化/生理作用

在各种研究应用中，鲑鱼精子DNA常被用作阻断剂。 已知它可以通过减少非特异性结合和背景信号来提高多AP测定的特异性和敏感性。

The Ku antigen consists of 70 and 80 kDa protein subunits (p70 and p80, respectively) that form the DNA binding component of a DNA-dependent protein kinase (DNA-PK). It is controversial whether the interaction of Ku with DNA is mediated by
