| 产品介绍 |
荧光素是一种常用的生物发光报告分子,用于荧光素酶表达的体内成像。这种萤火虫荧光素酶的底物以 ATP 和 Mg²⁺为辅因子,在有氧条件下发出特征性的黄绿色光,而在体内 37°C 环境下会转变为红光。由于该反应利用 ATP,因此还可通过检测其发光来指示能量或生命的存在,从而用作区分生死的染色剂。 Luciferin is a common bioluminescent reporter used for in vivo imaging of the expression of luciferase. This substrate for the firefly luciferase enzyme utilizes ATP and Mg²⁺ as cofactors to emit a characteristic yellow-green emission in the presence of oxygen, which shifts to red light in vivo at 37°C. Through the utilization of ATP, the reaction can be further used to indicate the presence of energy or life in order to function as a life-death stain. Luciferin is a common reagent used throughout the biotechnology field and specifically for in vivo imaging. Luciferase labeled tumor cells, stem cells or infectious diseases are often inoculated into research animals such as rats or mice for investigation. The injection of luciferin allows for the real-time, noninvasive monitoring of disease progression and/or drug efficacy in these model systems through Bioluminescence Imaging (BLI). Luciferin is also commonly used for in vitro research, including luciferase and ATP assays, gene reporter assays, high throughput sequencing and various contamination assays. |
