8pyDTZ

CAS No. : 2351898-91-2

MCE 站：8pyDTZ

产品活性：8pyDTZ 是一种吡啶基二苯基叔嗪 (DTZ) 类似物，也是 一种 LumiLuc 荧光素酶的 ATP 非依赖性吡啶基底物。8pyDTZ 表现出光谱偏移的发射并改善了水溶性。8pyDTZ 具有出色的生物相容性和体内敏感性，可用于生物体内发光成像。

研究领域：Others

作用靶点：Others

In Vitro: 8pyDTZ (1711 μM) enhances the water solubility by 13-fold from DTZ (131 μM). Compared to DTZ, 8pyDTZ (compounds 3c) is able to emit red-shifted chemiluminescence or bioluminescence. 8pyDTZ shows the most red-shifted emission and red-shifted photons can penetrate through tissue better.
LumiLuc-8pyDTZ in human embryonic kidney (HEK) 293T cells transiently expressing the luciferase is evaluated. The LumiLuc-8pyDTZ pair produces ?3-5-fold more bioluminescence than teLuc-8pyDTZ. To compare far-red emission intensities of bioluminescent reporters, HEK 293T cells in the presence of a 600-700 nm band pass filter are imaged. At substrate concentrations from 6.25 to 100 μM, LumiLuc-8pyDTZ consistently produces 1.6-3.9-fold higher photon flux than teLuc-DTZ. No ATP perturbation is observed from 8pyDTZ-treated, LumiLucexpressing cells.

In Vivo: LumiLuc-8pyDTZ pair is compared with several benchmark reporters in a tumor xenograft mouse model. LumiLuc-8pyDTZ shows high sensitivity and does not need organic cosolvents for in vivo administration. LumiScarlet-8pyDTZ is comparable to Akaluc-AkaLumine, the brightest ATP-dependent luciferase-luciferin pair, for detecting cells in deep tissues of mice.
