应用
L-012已被用作生物发光检测的探针,用于测定分离的小鼠肺中的活性氧(ROS)水平。
生化/生理作用
L-012是鲁米诺类似物,是培养物和动物体内广泛使用的活性氧和氮物质(RONS;ROS & RNS)化学发光(CL)探针。L-012显示出比鲁米诺、光泽精和MCLA显着更高的CL产量和灵敏度。L-012(LumH2)不是直接与超氧阴离子(O2−)反应,而是通过单电子氧化(在H2O2存在下由过氧化物酶催化)转化为LumH·自由基形式,然后与氧气(O2)反应生成O2−和L-012醌(q-Lum)。O2−依次与LumH·自由基反应,最终导致内过氧化物分解以发出发光。在较小的范围内,H2O2也可以与q-Lum反应产生发光。尽管对NADPH氧化酶衍生的RONS不是特异性的,但L-012也通常用于筛选NADPH氧化酶抑制剂。

An enhanced chemiluminescence reaction has been incorporated into an enzyme immunoassay (EIA) for human basic fibroblast growth factor (hbFGF). We developed a new luminol derivative, designated L-012 and a new enhancer, 4-(4-hydroxyphenyl)thiazole. Using these compounds, the detection limit of hbFGF

L-012, a luminol-based chemiluminescent (CL) probe, is widely used in vitro and in vivo to detect NADPH oxidase (Nox)-derived superoxide (O2(*-)) and identify Nox inhibitors. Yet understanding of the free radical chemistry of the L-012 probe is still lacking. We

Oxidative injuries, such as those related to reactive oxygen species (ROS), have been implicated in various retinal and optic nerve disorders. Many ROS detection methods have been developed. Although widely utilized, many of these methods are useful only in post
Redox biology, 12, 35-49 (2017-02-18)
Reactive oxygen and nitrogen species (RONS such as H2O2, nitric oxide) confer redox regulation of essential cellular functions (e.g. differentiation, proliferation, migration, apoptosis), initiate and catalyze adaptive stress responses. In contrast, excessive formation of RONS caused by impaired break-down by

The role of neutrophils in solid tumor metastasis remains largely controversial. In preclinical models of solid tumors, both pro-metastatic and anti-metastatic effects of neutrophils have been reported. In this study, using mouse models of breast cancer, we demonstrate that the
