應用

ANS 与环糊精形成包合物。 这种模型系统可用于模拟生物识别,并且可以通过测量游离 ANS 向络合 ANS 的荧光变化来研究。 当 ANS 进入环糊精的疏水核心时,它的荧光增加。在钠选择性光纤传感器的试剂阶段使用。 试剂相还含有铜(II)聚电解质,其在不存在钠的情况下与 ANSA 结合,并淬灭荧光。 在钠存在下,ANSA 形成阳离子复合物,产生离子对,使其发荧光。ANS 通常掺入二嵌段聚合物中,并可通过局部环境的变化(即温度,pH 等)释放。ANS 通常用作荧光探针以研究表面活性剂和两亲聚合物的分子组装,因为其最大发射量的蓝移表明该探针位于极性较低的介质中。用于蛋白质研究的荧光探针,使用稳态和动态荧光测量等方法。

4-Hydroxynonenal (4-HNE) is a reactive α,β-unsaturated aldehyde produced during oxidative stress and subsequent lipid peroxidation of polyunsaturated fatty acids. The reactivity of 4-HNE towards DNA and nucleophilic amino acids has been well established. In this report, using proteomic approaches, liver

In our study, we showed that at a relatively low concentration, H(2)O(2) can irreversibly inactivate the human brain type of creatine kinase (HBCK) and that HBCK is inactivated in an H(2)O(2) concentration-dependent manner. HBCK is completely inactivated when incubated with
