Background:

L 012 sodium salt is a chemiluminescent probe [1].

L 012 sodium salt is a new chemiluminescent probe. In activated EoL-1 cells which generated reactive oxygen species (ROS), treatment with L-012 generated a significant chemiluminescence. While, superoxide dismutase (100-300 U/ml) abolished the chemiluminescence, which suggested that the main ROS detected was O2- [1]. In cultured endothelial cells, phorbol 12-myristate 13-acetate (PMA, 1 μM) caused an 2.8-fold increase of L-012 chemiluminescence. Vanadate (100 μM) increased the chemiluminescence up to 17-fold. These results suggested that the increase of superoxide produced by NAD(P)H oxidase [2].

In human oral cavity and blood and rat peritoneal cavity, L-012 reacted with ROS generated by activated neutrophils and generated strong chemiluminescence, which was higher than that of MCLA [3]. In nonobese diabetic mice and K8 knockout (K8(-/-)) mice, treatment with dextran sulphate sodium generated an increased L-012 chemiluminescence which detected reactive oxygen and nitrogen species (ROS and RNS) [4].
