| 产品描述 | DPPH (2,2-Diphenyl-1-picrylhydrazyl) is a stable nitrogen-centered radical that can be used to measure the free radical scavenging activity of antioxidants. DPPH has a single electron, so it can accept either an electron or a hydrogen ion, and has a maximum absorption at a wavelength of 517 nm. |
| 靶点活性 | PNT2 cells:1400 µM |
| 体外活性 | 方法: PNT2 细胞用 DPPH (156-5000 µM) 处理 24 h,通过 MTT assay 检测细胞活力。 |
